Motorcycle IZh Planet Sport Rotax - developed by the Izhevsk plant

Design of Planet Sport from Izhmoto

The technical characteristics of the PS were amazing.
This was the first serial steel horse in the USSR with a separate engine lubrication system. Moreover, the latter was the own development of the designers of the Izhevsk Motor Plant. The bikes released from the assembly line in 1974 could boast of this feature. A characteristic sign of the presence of such know-how in the IZH Planet Sport motorcycle is the presence of the letter “M” in its number. The PS engine from Izhmoto had a slightly increased displacement compared to previous models from Izhevsk. It was 349 cm³. It is noteworthy that the iron horse received a Japanese Mikuni carburetor from the factory. This allowed the bike to produce the coveted 32 hp. and 6,700 rpm.

With a dry motorcycle weight of 135 kg, it could boast enviable technical characteristics (237 horses per ton of weight). This was almost double the figure for the Jawa 350 “634”.

Izh PS reached 100 km/h in 11 seconds. The engine of this horse was attached to the frame using rubber cushions. For the 1970s, this was a real technical innovation. In addition, the bike was actively equipped with Japanese electrical equipment and even optics. The same models of the IZH PS motorcycle that were equipped with a domestic carburetor (K 62M) could develop slightly less power of 28 horses. Since 1978, Soviet electrical equipment and a domestic speedometer have been installed on this iron horse. These bikes had larger spoke diameters.

Technical characteristics of IZH Planet Sport

During 1975-1983.
the bike often went through design changes. It was modernized and improved. Therefore, all Izh PS motorcycles do not have the same technical characteristics. Yet some of them did not change. The length of the bike is 207 cm. Its width reaches 79-81 cm. At the same time, the height of the bike is 115 cm.

The maximum recommended speed of the Izh PS motorcycle is 140 km/h. This bike consumes 3.5 liters of fuel per 100 km (at a speed of 60 km/h). In the city, consumption increases slightly and reaches 7 liters.

The braking distance of the Izh Planet Sport motorcycle is still significant and amounts to 16 meters at a speed of 60 km/h. At a speed of 30 km/h, the motorcycle will need only 7 meters to come to a complete stop.

The technical characteristics of the PS Izhmoto engine are also impressive. The engine of this two-wheeled sportbike has a two-stroke type of operation. Its three-channel blowing has proven itself well.

One cylinder is more than enough for this bike to develop considerable power. The diameter of the latter is 76 mm. The Izh Planet Sport motorcycle has a power unit that has a fairly high compression ratio (10.5). The cooling system actively uses oncoming air flows. The filter for purifying air before it is supplied to the mixture is of the dry type. It was supplemented with a paper element.

The IZH PS motorcycle was amazing

First of all, the gear ratios of this bike’s gearbox are amazing. In addition, the motorcycle received improved shock absorption as a gift from the designers. The electrical equipment at PS Izhmoto is surprising for such an old Planet model. The bike has an on-board network with a voltage of 12 volts. The three-phase alternating current generator is capable of delivering 14 volts and a power of 100 watts.

Note that the very first iron horses of this series were equipped with foreign batteries.

The very first Izh PSs were supplied with Italian Magnetti-Marelli spark plugs. Often these were “NGK” spark plugs, which are recommended for use at high speeds (from 100 km/h). At the same time, the gasket was removed from the cylinder head.

The fuel tank of the Izh Planet Sport motorcycle had a volume of 14 liters. AI-93 gasoline was considered the most suitable for refueling this bike. The oil tank of the iron horse held 1.5 liters.

Adjusting the carburetor of the IZH Jupiter motorcycle

Setting up Peker carburetors on the IZH Jupiter 5 motorcycle is carried out as follows. First, we check the tightness and integrity of the air filter. Then we check the serviceability of the ignition. After this, we proceed to adjustment, the algorithm is as follows:

A few words about setting up the Jikov-2928CE carburetor. The idle speed setting here is similar to that of the K-65. The only differences are in the location of the adjusting screws. In Jikov they are conveniently located on the side of the carburetor (the one that is screwed in at an angle is responsible for the height of the throttle valve).

The fuel level in the float chamber should be 9 ± 1 mm. Due to the design features of this carburetor, adjusting the composition of the fuel mixture to reduce the dip when opening the gas sharply is done by moving the throttle needle up (on the K-65 in this case, we turn the quality screw).

Adjustment video

To understand the basics and nuances of adjusting the carburetor of the IZH Jupiter motorcycle, we recommend watching an interesting video. The author tells in detail how to adjust the K68 carburetor on the IZH Jupiter 4 motorcycle. He shows and talks about all the nuances and features.

Motorcycles "Java"

Another legendary Jawa motorcycle dates back to 1929. This brand of road transport belonged to a Czechoslovak company and was the dream of many Soviet motorcycle enthusiasts. Motorcycles were used not only for everyday travel, but also participated in various racing competitions. In the 21st century, the production of Java has not stopped; some models are still in demand.

Jawa 350 Classic

The motorcycle is based on a 2-cylinder, 2-stroke system with a 4-speed gearbox. There is no connection between gasoline and oil thanks to a separate lubrication system. The motorcycle frame is strong, which allows you to load motor vehicles up to 200 kg. It is possible to attach a car seat.

If we compare the Jawa 350 Classic 638 model with others, more expensive and equipped, it wins in several respects: maintenance is simple and inexpensive, fuel consumption is low, spare parts are available for sale at a low price.

Technical characteristics of "Java" 350 classic:

• dimensions – 2110×750×1070;
• engine capacity - 343.5 cubic meters. cm;
• power – 23.1 l. With.;
• maximum speed – 125 km/h;
• gasoline consumption per 100 km – 4 liters;
• manual gearbox.

Jawa 350 Classic Sport

“Classic Sport” is an improved version of Jаwa 350 Classic. It was presented in 2022 at the Moscow Motopark exhibition. You can distinguish the model from other Java motorcycles by the “outdated” design of London in the 60s, when street motorcycle racers converted inconvenient and bulky motorcycles for themselves, removing everything unnecessary. The two-wheeled vehicle turned out to be light and maneuverable, with streamlined elements.

Jawa 350 Classic Sport is designed for solo travel and is equipped with one comfortable seat. The low steering wheel allows you to comfortably take the position of the rider, fully concentrating on the ride. The “rarity” of the motorcycle is reminiscent of its classic elements: a wide chrome exhaust pipe, a round headlight and a traditional red body color.

The motorcycle has a lot of advantages that make for a comfortable and maneuverable ride: a 343 cc engine, a separate lubrication system, a reliable disc-type brake system, a laconic dashboard and an automatic starter.

Specifications:

• engine capacity – 343.5 cubic meters;
• number of cylinders – 2;
• number of cycles – 2;
• power – 23 l. With.;
• maximum acceleration speed – 125 km/h;
• gasoline consumption per 100 km – 4 liters;
• air cooling system.

Jawa 350 Lux

The presented model is a classic version of a street class road motorcycle. It combines elements of older models, but also has individual modern features. The front of the motorcycle has a classic single headlight, and the electronic instrument panel is simple and understandable even for novice motorcyclists.

The basis of the two-wheeled design is a strong steel alloy frame. Its rigidity improves maneuverability on uneven roads, makes the vehicle maneuverable and increases load capacity. The holistic appearance of the Java 350 Lux clearly resembles a “classic”.

Specifications:

• dimensions – 2110×750×1070 mm;
• engine capacity – 343 cubic meters. cm;
• number of cycles – 2;
• number of cylinders – 2;
• power – 23.1 l. With.;
• maximum speed – 125 km/h;
• Fuel consumption per 100 km is 4 liters.

Jawa 660 Sportard

The most powerful Java model in terms of technical equipment is the 660 Sportard. The engine capacity of 600 cubic meters affects the ability to reach speeds of up to 250 km/h. The motorcycle covers distances along the highway easily and maneuverably. For beginner motorbikers, this is an excellent tool - flexible and playful. And externally, the 660 Sportard looks more aggressive and modern than the classic versions.

The technical characteristics have their own characteristics: the power plant is “single-barrel”, equipped with an electronic injection system - EFI

The frame frame has a high degree of rigidity, and this is an important condition for off-road driving - the motorcycle does not twitch and is easy to control. The upgraded suspension of the bike allows you to take turns at the same speed without pressing the brake pedal

The technical specifications are as follows:

• dimensions – 2100×760×1250 mm;
• cylinders – 1;
• number of measures – 4;
• engine capacity – 651.9 cubic meters. cm;
• power – 48 l. With.;
• gas tank volume – 17 liters;
• Manual transmission – 5-speed.

Project “Boosting of the IZh “Planet-5” engine”

Topic: “Boosting the IZh “Planet-5” engine”

Relevance of the topic.

There is a large amount of technology on the modern market. This technique is expensive and has a complex engine design. Soviet IZH engines lag behind their foreign counterparts in their characteristics, but they have a simple design and are easy to modernize. Several decades ago, domestic motorcycles were in great demand, both in Russia and in neighboring countries. The main buyers of such equipment were rural residents. The reason for this interest is clear - simplicity of design and low price. In villages remote from the city there were no specialized centers for repairing motorcycles, so local residents had to solve engine repair problems on their own. They managed this without any problems. Over time, the appearance of our country has changed, and the needs of modern man have also changed. Nowadays it is very rare to see a Soviet motorcycle on the streets of a village, much less a city. This is due to the fact that modern Russian motorcycles are much inferior in their technical solutions to foreign manufacturers. To improve the performance of my personal motorcycle IZH “Planet5”, I decided to upgrade its engine.

Hypothesis:

boosting the Soviet IZH Planet engine will help change its technical parameters, which will ensure stable and uniform operation of the engine, both at idle and at high speeds, increase power, and balance the fuel supply to the cylinder.

Target:

boosting the IZH "Planet" engine to further improve the quality of its operation.

Tasks:

1. Study the literature on this issue.

2. Select the main components for boosting the engine.

3. Find the necessary elements to boost the engine and evaluate the economic benefits.

4. Upgrade the engine.

In the process of work I used the following research methods

:

1. theoretical (modelling, analogies, comparative analysis, generalization, integration)

2. empirical (conducting an experiment).

3. mathematical (data visualization method)

An object:

motorcycle IZH "Planet-5".

Item:

engine IZH "Planet-5".

Conclusions:

1. The literature on this issue has been studied.

2. The main components for boosting the engine were reasonably selected.

3. Selected engine components of the IZH Planet-5 motorcycle have been modernized.

Several units underwent modernization, which led to the following results:

1) the engine runs stably at idle and high speeds;

2) engine life has increased;

3) engine speed increased;

4) vibration decreased;

5) 92 grade gasoline can be used as fuel.

As a result of this work, the IZH Planet 5 engine was boosted.

Serial production of domestic motorcycles is closely related to the activities of Pyotr Vladimirovich Mozharov. This outstanding mechanic and talented designer in 1928 submitted a proposal to the government to produce serial motorcycles at factories in the city of Izhevsk. It was under his leadership that the first motorcycles under the IZH brand were created, tested and put into production. By the end of 1979, Izhevsk became the most important motorcycle manufacturing city in the former USSR. The conveyors of his factories could supply 350 thousand units of equipment per year. It was during these years that the IZH “Planet” motorcycle, famous throughout the country, appeared. This series gave birth to a lot of successful machines, unpretentious in operation and reliable in any conditions of use. A striking example was the beloved IZH “Planet 5” motorcycle.

IZh "Planet-5"

— a middle-class road motorcycle designed for riding on roads with different surfaces. Produced by the Izhevsk Machine-Building Plant from 1987 to 2008. The unpretentious and relatively inexpensive motorcycle model enjoyed deserved popularity. During the production process, the motorcycle was upgraded many times in terms of chassis and engine. It also has several configuration options.

The engine installed on these models has relatively high thrust at low speeds. It is possible to attach a side cargo or passenger trailer, or a universal cargo module to the motorcycle. It can also optionally be equipped with a luggage rack and knee guards.[1]

To reduce the clutch release force, the motorcycle uses a multi-plate (6 pairs) clutch with reinforced drive disc splines and a cam clutch release mechanism. Vibration dampers for the cylinder fins, together with a larger volume air cleaner, are designed to reduce the noise level produced by the motorcycle. [1]

The IZH Planet-5-01 motorcycle is a further modernization of the IZH Planet-5 motorcycle.[2]

The motorcycle began production in 1995, production was completed in 2007. Some of the technical solutions for the motorcycle were licensed and were originally intended for the promising IZH-Orion model.

The electrical system uses a permanent magnet generator with a contactless ignition system that operates independently of the battery, with automatically adjustable ignition timing.

The engine is equipped with a separate lubrication system pump, which eliminated the need to prepare and use a mixture of gasoline and oil in the motorcycle’s power system.

The gearbox is four-speed with an eccentric clutch release mechanism and a reinforced motor chain.

The front wheel brake is hydraulically driven disc or mechanically driven two-cam. The wheel suspensions use shock absorbers with improved characteristics and rebound springs, and the rear wheel suspension arm is mounted on rolling or sliding bearings. The kinematics of the rear wheel brake drive have been changed.

Technical parameters of the motorcycle.

Engine Specifications

Engine problems and disadvantages:

1) Engine vibration;

2) High fuel consumption when raising the carburetor needle;

3) Weak acceleration of speed;

4) The piston is stuck to the cylinder walls;

5) Defective contact ignition (the spark is ahead of the piston).

Work plan.

1) Replacement of standard bearings with Japanese ones (not lower than quality 6) from AOUO. Replacing the bearings is necessary, since the speed after boosting the engine will increase, and standard domestic bearings of low class and quality will not withstand the increased speed and load. Replacing bearings will increase engine life.

2) Replacing the standard piston. When the engine is running, the standard piston is subject to sticking against the cylinder walls, which gives negative positions. This action leads to the destruction of the cylinder mirror. The standard piston can be replaced with a Japanese one.

3) Increasing the degree of compression of the combustible mixture. Increasing the compression ratio is one of the main methods for increasing engine power. This way you can get more output from the same engine size. In a word, the power will increase, but the consumption will remain the same. In this case, you will have to refuel with high-octane fuel.

4) Improve the balancing of the crankshaft, as well as its structure. Balancing the crankshaft will allow it to spin up to high speeds.

5) Increase the volume of the cylinder by boring the channels. After this, the filling of the combustible mixture will occur quickly and evenly. The engine power will increase.

7) Install the Mikuni carburetor. Installing this carburetor will increase the fuel supply, which will allow a balanced supply of fuel to the combustion chamber.

Electronics change.

Result.

When finalizing and changing the technical parameters of this engine, we have:

1) The engine runs stably at idle and high speeds;

2) Engine life has increased;

3) Engine speed has increased;

4) Vibrations have decreased;

5) You can use 92 grade gasoline as fuel.

In addition to its main purpose - to ride, the IZH "Planet - 5" motorcycle is an excellent assistant and a wonderful help in household farming.
The unpretentious vehicle has excellent maneuverability, and when equipped with a side or other universal trailer, it is capable of transporting up to 250 kilograms of various cargo at a time. It is not uncommon that, after modernization and alteration, the IZH “Planet -5” motorcycle was turned into a snowmobile, and sometimes even a mini-tractor. The modern market offers a large selection of different models of motorcycles for every taste and budget, however, I would like to hope that the new Izhevsk models will have as many admirers and lovers as the old, but still tenacious IZH “Planet-5”.

Three improvements to the Java 634 for motorcycle tourists

Three proposals On the YAVA-634 motorcycle, for more convenient maintenance, I introduced a number of improvements that may be of interest to motorcycle tourists. Here are three of them: 1. To prevent dirt from clogging the gap between the wheel and the shield when traveling on dirt roads, I raised the shield by installing an extension (photo 1) made of sheet steel. 1. This is what the shield bracket extension looks like. 2. I secured the panel under the saddle (photo 2). on which I placed a ground switch 2 (toggle switch), a block 3 with a fuse, two sockets 4 for connecting the battery, a socket 5 for connecting a lamp mounted in the base of the saddle (it illuminates the seat space), and two sockets 6 from which you can take power supply for a portable lamp, receiver, vulcanizer, etc. 2. Underseat space: 1 - panel: 2 - toggle switch; 3 — block with fuse; 4 — sockets for connecting the battery; 5 - socket for connecting a lamp embedded in the base of the saddle...

Elimination of loose brake pedal on an IZh motorcycle with a sidecar

Reliable fastening On IZh motorcycles with a sidecar equipped with a brake, the pedal soon becomes loose. In this case, the order of operation of the brakes of the motorcycle and the trailer is disrupted, which is why the crew skids to the side when braking, especially sharply. In addition, the adjustment of the brake light switch changes. To eliminate this drawback, I turned out axle 9 (see Fig. “b”) and attached the brake pedal to it, drilling a hole in the support plate 2 of the frame to 12 mm. Since then this unit has been working properly. Brake pedal mounting unit: a - factory version; b - revised version; 1 — brake pedal; 2 — frame support plate; 3 — M10 bolt; 4 - bushing; 5 - spring washer; 6 — nut M10; 7 — washer; 8 — M12 nut; 9 - axis. This modification will not hurt those who travel without a stroller. Gorky city GRACHEV 1987N09P33

Two forces more powerful. Boosting the IZH-36/IZH-Planet engine

Increasing engine power is a question of interest to many motorcyclists. And this is understandable: the dynamic and other parameters of a motorcycle are directly dependent on the power of its engine. We have already told you (“Behind the Wheel”, 1967, No. 1) how to increase the power of the IZH Planet engine to 18 hp. With.

Rice. 1. Changing the diameter of the carburetor diffuser Some readers, who are not able to complete the entire amount of work recommended in the article, ask about simpler methods that allow them to obtain at least a small (two to three times the power) increase in power. In the published article by engineers V. Abrahamyan, A Maksimov and B. Lezhnev owners of IZH 36 and IZH Planet motorcycles are given recommendations on how, by making minor changes to some components and parts of the engine, increase power to 15 hp. The design changes proposed by the authors do not increase fuel consumption and have virtually no effect on the durability and reliability of the motorcycle. The main means of increasing engine power…

Motorcycle IZH Jupiter 4. About operation (after 4 years)

Lessons from Jupiter 4 Interested readers will remember that four years ago the editors of Za Rulem received a Jupiter-4 motorcycle with a sidecar from the Izhevsk plant for consumer testing. We described our impressions received in the process of getting to know this car in sufficient detail in No. 11 for 1981 and No. 7 for 1982. Subsequent trial operation allowed us to accumulate many observations, comments and suggestions on the design of the motorcycle, which we intended to talk about from the pages of the magazine. Fortunately, we did not have the chance to do this. It was fortunate: at the same time, factory specialists intensively improved their car, as a result of which a new model was born - “Jupiter-5” (readers met it in the January issue of “Behind the Wheel” of this year). In the new modification, in one way or another, almost all the issues that arose during the tests of IZ Jupiter-4 were resolved. To what extent...

dim-on42 › Blog › Izh-Enduro from K16

Good day to all!

Lately, I started visiting drive2.ru quite often and noticed that there was a topic related to motorcycles (either I hadn’t noticed it before, or it didn’t exist at all). As an ardent fan of two-wheeled vehicles, I really liked this section, it’s a pity that there aren’t many entries there. I decided to contribute my “5 cents” myself, maybe someone will be interested.

So, I decided to dedicate this entry to my former, quite interesting motorcycle - a clone of Izh-K16 and Izh-Planet-5.

The story began with the fact that I really wanted a motorcycle that I could ride anywhere. Foreign cars were not considered in principle; I was a student, although I worked, but every penny counted. This is an expensive pleasure. Well, I decided to try to do something similar with my own hands, as simple as possible and with spare parts available. Initially I wanted to take a frame from a cross-country CZ 250 or 380 (aka 500), but after monitoring the prices, I realized that this was far from a budget option, and the spare part was a huge strain. I didn’t even think twice about the engine; I decided to use the old, time-tested unit from Planet-5. An unpretentious engine, low fuel consumption, the availability of spare parts in any motorcycle shop and market, and good traction at low speeds will allow you to climb steep hills and ford, especially with correctly selected drive and driven sprockets.

One fine evening I met an old friend, and a conversation began about motorcycles. It turned out that for many years he had had a K16 motocross bike with a seized engine in his garage, littered with all sorts of rubbish. Without thinking twice, the very next day I went to see it. Everything worked out fine and for a small fee he ended up with me.

Tuning Izh Planet Sport

Making changes to the design of a motorcycle is impractical for a number of reasons:

1. The resource of many components and assemblies is small. For this reason, it is almost impossible to improve their characteristics without causing damage.
2. An Izh Planet Sport 350 restored to its original condition is valued significantly higher than its tuned versions.

However, if there is a desire, something can be done. Many athletes participating in cross-country or circuit racing competitions modified the Izh Planet Sport engine, making various changes to its design. A frequently asked question is how many cubic meters can the engine capacity be increased by.

Engine tuning (boosting)

When boosting the engine, the sports team masters altered many things, from the connecting rod and piston group to the exhaust system. The maximum that could be obtained by pressing in a liner from a CZ 500 and using the piston that came with it was a little over four hundred cubic centimeters of working volume.

But such boosting of the Izh Planet Sport engine requires serious professional skills and sophisticated equipment. The thin walls of a standard cast-iron sleeve pressed into an aluminum cylinder do not allow the engine to be bored up to 500 cc.

The exhaust system cannot cope with the removal of the increased volume of exhaust gases, and the support bearings cannot cope with the increased loads. All the talk that there was a factory version of the Izh Planet Sport 500cc is nothing more than a fairy tale. But boring a cylinder is not the only way to increase power and add agility to a motorcycle.

DIY tuning

Installing a new carburetor is a proven way to improve the performance of the Izh Sport without making significant changes to the design. Over the years, Mikuni has released many new, increasingly advanced models with a diffuser diameter of 32 mm.

Engine tuning can be done in other ways without affecting its mechanical components. Starting and stable operation of single-cylinder engines has always presented certain problems, which can be solved by installing electronic ignition on the Izh Planet Sport. Such kits are produced by several manufacturers, and their installation does not take much time.

When using BKSZ with power units of other modifications, you should be very careful. When installing the ignition from a Minsk motorcycle on the Izh Planet Sport, you must remember that the crankshafts of the engines of these machines rotate in opposite directions. The wires going from the coil to ground and the switch will have to be swapped. Such an engine modification is quite justified.

Improvement of technical parameters

Tuning to increase power.

The design of the motorcycle engine allows for tuning to increase its power. One option is to re-press the engine crankshaft and change the support bearings. Usually, secondary shaft bearings from a Java motorcycle were installed as new bearings. This restoration made it possible to achieve an increase in engine power of the IZH Planet - 5 by 10-15%.

The next option for adding power was to increase the cylinder volume. For this purpose, its upper part was cut off and the sleeve was bored to 76 mm. Then the appropriate piston was installed, usually a piston from a Planet Sport motorcycle was used.

Increasing the speed of the motorcycle.

After this operation, the speed of the motorcycle increased, according to some sources, to 160 km per hour. Therefore, work to increase engine capacity was carried out by owners who planned to operate their vehicle mainly on highways.

The most difficult technical tuning option for adding power to the IZH Planet - 5 is the installation of supercharging. For this purpose, an exhaust valve is installed, the device of which corresponds to the analogues on the sports versions.

Then an exhaust resonator is installed, which has sharply directed parameters. Its task is to create a wave backpressure of the fuel mixture. Next, a spool valve is installed to obtain asymmetrical phases of engine operation, which avoids the direct release of the spent mixture.

Performing supercharging on the engine of the Fifth Planet is a rather complex process and therefore is not widely used.

Improved grip.

As engine power increases, it is necessary to carry out work to improve the clutch. Under standard conditions, the standard clutch works reliably.

But as the load increases, the risk of “burning” it and subsequent repairs increases sharply. The main steps for tuning the clutch come down to replacing standard discs with larger metal ones. Typically, such discs are made of two millimeter iron.

The use of thicker metal discs reduces slippage, warping, breakage and provides greater heat transfer.

Exterior design of a sports motorcycle

The appearance of this vehicle is very reminiscent of Japanese vehicles of the mid-60s, this can be seen in the shape of the front wing, elegant front hub, and dynamic rear wing. You can immediately feel the wind from the east, because the Izh Planet Sport is very similar to the ’66 Suzuki T250 Super Six, 1970 Yamaha 350R5 and 1966 Kawasaki A1 Samurai.

The bike turned out to be very modern and immediately made it clear that it is intended for high-speed riding, and not for trips to the country. And even today Planet Sport looks decent, like a real classic bike. The color scheme further added to the sporty appearance of the motorcycle; the very first Planet Sport were produced in bright yellow and orange. Combining these bright colors with a black frame and shiny nickel fenders, yokes, engine cover and headlight bezel made for a very cool looking bike. Many girls on motorcycles started with this sports byte from IZH.

Characteristics of a sports Soviet motorcycle

Izh PS not only looked like a modern bike, the technical components were also different and seriously different from other IZh motorcycles, except for the chain and gearbox parts, of course.

One of the most important innovations was that Planet Sport was equipped with a separate engine lubrication system; at that time, such a technical concept seemed unrealistic. The 350cc engine installed in the “Sport” with a Japanese Mikuni carburetor allowed the motorcycle to develop a power of 32 hp. With. at 6700 rpm.

The weight of Planet Sport was 135 kg, and at that time these were very good figures. For example, the Jawa-350/634, popular in those years, with a power of 22 horses, weighed 155 kg. That is, it is clear that Java had no chance in speed against the sporty Izh. Another innovation was that the PS motor was secured in the frame using rubber pads.

The very first Izh Planet Sport 350 were equipped with the same Japanese Denso electrical equipment as on Yamaha. That is why for the first time a Soviet motorcycle met the UNECE lighting requirements.

The dynamic performance of the new Izh was at a high level even by the standards of the USSR - the maximum speed was 140 km/h, and acceleration from zero to hundreds in just 10 seconds seemed fantastic.

Later they began to produce IZhi Planet Sport with a domestic carburetor, which had a smaller diffuser, after which the power of the PS decreased and became 28 horses. You can distinguish later versions from early ones by the elongated rear fender and slightly curved exhaust pipe, although in early versions it was straight.

The sports IZH was produced for ten years

Serial production of this motorcycle began in 1974. The first batch of 500 cars was sold in the USSR in the summer of 1975. All motorcycles of the first batch were equipped with Japanese electrical equipment and a separate lubrication system. By 1979, Planet Sport was no longer equipped with imported components, and the quality of the main parts even deteriorated slightly.

That is why Soviet motorcyclists valued motorcycles of the first years of production best; the price for early “sports” was higher than for later ones even 10 years later.

Sports IZhi were produced until 1985, and then were removed from the production line. These days it is very difficult to find a “sport” that is well preserved. In Russia, for a working motorcycle of early models they ask about 1000 Baku rubles, and sometimes more. But it is worth the money, as it is considered an exclusive Soviet motorcycle.

And here is the video test drive:

Made in USSR + Japan

It is interesting that all the main components and assemblies were domestic (except perhaps for the Japanese carburetor), that is, our own technologies made it possible to implement any modern designs - and to do this in mass production and with the expectation of long-term operation. Which, in fact, is not surprising, because IzhMash at that time was a defense complex enterprise. Only minor components of IZH PS were purchased abroad - lighting equipment and electrical appliances.

The Avtoexport advertising poster shows an experimental motorcycle; it was distinguished by its engine and cladding parts.

Imported parts provided the new product with a marketable appearance: style, design, neatness of finishing - what we really had problems with. According to the recollections of IzhMash veterans, in the first year of production (1973 - 1974) 30 thousand sets of 12 units of components each were purchased from Japan.

In the second year, by the way, the Japanese raised the price 2.5 times, purchased spare parts again, but in the end this played a role and the later PeEs lost imported parts, losing not only the “foreign” finish, but also 4 liters. With. power.

Motorcycles "Minsk"

Motorcycles of the Belarusian brand "Minsk" began to be produced in 1951, and in 2007 the manufacturing plant became private from a state-owned one.

Minsk D4 125

This model is simple and economical, but at the same time fully adapted to the roads of Russia and the CIS countries. The modern design fits perfectly into the traffic flow of the vehicle. The motorcycle is light and maneuverable, with good and smooth shock absorption.

The vehicle has a 125 cc engine. cm and a capacity of 10.2 liters. With. The built-in electric starter responds instantly to starting. The external design is individual. Dimensions – 2100x1110x770 mm.

Minsk S4 125

Minsk C4 125 was released in 2008. Light in both weight and control, maneuverable, inexpensive - this transport is chosen by young people and summer residents. It makes a good first bike for new riders, although its understated appearance may put some off at first glance.

The C4 125 model has a number of advantages:

• low cost;
• low fuel consumption;
• small dimensions and weight;
• adaptation to temperature changes.

There are also disadvantages:

• fastenings are unreliable;
• small mirrors contribute to poor visibility;
• The included tool kit does not fit the motorcycle;
• the electric engine start button is located at an inconvenient level;
• small fairing.

Minsk TRX 300i (tour-enduro)

The Minsk TRX 300i, which is more modern in design, attracts attention with its bright and sporty appearance. It embodies the enduro qualities of European manufacturers, which significantly distinguishes it from its Belarusian compatriots

This motorcycle is designed for long trips on a variety of road surfaces.

The 4-stroke engine is started using an electric starter. Movement is carried out by a 6-speed manual transmission. The transport is designed to transport 2 people.

Characteristics:

• dimensions – 2080/825/1230 mm;
• weight – 155 kg;
• front suspension – telescopic fork;
• rear suspension - mono shock absorber.

MINSK RX 250 (cross)

The cross-country “Belarus” is the latest development of the Minsk manufacturer. A special feature of the motorcycle is that it is assembled from parts from leading companies:

• Domino controls;
• Acerbis plastic;
• Leo Vince muffler;
• Dell'Orto carburetor;
• professional Fast Ace suspension;
• DID circuit

The wheels are equipped with aluminum rims with spokes made of durable metal alloys. The RX 250's exterior is bold and sporty. The model attracted the interest of avid crossers, so in the 2011-2012 season the motorcycle took part in the “Belarusian Motocross Championship” and proved itself to be a reliable and serious racer.

Specifications

Most of the Izh Sport components were produced in the USSR, although some parts were imported: a Japanese Mikuni carburetor, Hungarian optics from Pannonia, an Italian Veglia Borletti speedometer and some other little things. The technical characteristics of the Izh Planet Sport 350 were excellent; the thrust-to-weight ratio of the motorcycle was almost twice that of the super-popular Jawa 350, providing acceleration from 0 to 100 km/h in 11 seconds! The motorcycle was so reliable that there were rumors among Soviet bikers that it was originally developed exclusively as an export model. The service life of the CPG, according to reviews, reached 50-60 thousand kilometers, which is a record for a 2-stroke engine. The maximum speed of the Izh Planet Sport is 140 km/h.

Engine

On Izh Sport in the first years of production, the power reached 32 horsepower, but later it was reduced to 28 hp. for the sake of efficiency and engine life (volume - 340 cm³). The separate lubrication system and engine mounting on rubber mounts implemented in this model were original innovations, thanks to which the bike successfully competed with Japanese and European models in the markets of Great Britain, Finland and other countries. Excellent engine performance combined with high build quality made this bike incredibly popular.

Transmission

The bike is equipped with a classic 4-speed gearbox, simple and reliable. Gears change in the usual manner, 1-N-2-3-4. The gear ratio of the top, fourth gear is 1.0, and you can safely switch to it already at 70 km/h - it will ensure smooth acceleration.

Chassis and brakes

Despite some innovative solutions, the Izh Planet Sport characteristics corresponded to its time. That’s why the motorcycle got a regular, welded frame, and the fork is a simple rodless telescope with a free play of 150 mm. At the rear there is a swingarm with a stroke of 95 mm, so the suspension cannot be called soft. The brakes are drum brakes, not very effective, and the declared stopping distance at a speed of 60 km/h is at least 16 meters.

Electronics

The electronic content of this model was partially imported. Thus, the sound signal was produced at the Japanese company Nikko, the ignition switch was borrowed from Jawa, original Magneti Marelli spark plugs came to the Soviet Union from sunny Italy, and no less original batteries came from the Land of the Rising Sun. But in general, the electrical circuit of the motorcycle is simple and easy to understand.

Weight and dimensions

The dry weight of Izh PS is only 135 kg. Thanks to this, the bike has good dynamics and does not forbid some recklessness, which, in fact, is why Soviet motorcyclists fell in love with it. Its dimensions are appropriate; this model is more compact than Izh Jupiter 5 or Planet 3.

Controllability

For bikers accustomed to modern motorcycles, riding an Izh PS may seem unusual. The bike handles well, but the steering angles are wide and you can easily drop the bike, especially when turning at low speed. This feature is worth keeping in mind.

Planet 3 tuning

Of course, many owners of IZH Planet 3 tune their motorcycle. But not everything that you want is useful. For example, boosting the engine leads to rapid wear and tear of the unit and inevitable repairs, since it is simply not designed for such power. But converting the power supply system from contact to non-contact, strengthening the frame, installing a sliding contact with the corresponding board are completely compatible with this technique. Although modern owners do not think twice, since IZH Planet 3 today is sometimes available for free. They boldly experiment. But the rare and reliable motorcycle still lives a full life. And it is in great demand among fans of metal motorcycles.
