Kyiv Legend: technical characteristics

The original equipment of the MT Dnepr 11 is distinguished by the characteristics given in the table below:

The main differences of the Dnepr MT 11, visible in the photo and in reality, are its impressive dimensions and weight, as well as the external reliability of the design. If we compare the motorcycle with other, more modern equipment, we can say that the power for its 650 cc engine is insufficient.

However, almost none of the new products from motorcycle manufacturers from around the world can compare in off-road capability with this model.

The large carrying capacity of the Dnepr-11 makes it universal, since it can transport not only several passengers, but also small-sized items with significant weight.

In conclusion, it is worth advising you to watch a video with the Dnepr MT 11, as well as its modifications, in order to verify the versatility of this technique.

Heavy motorcycle MT-11 "Dnepr"

Today we will talk about a powerful, heavy motorcycle for real men - the MT-11 Dnepr, which helped Soviet citizens both in villages on the roads and in the city when it was necessary to transport a heavy load.

So, you have become infected with a thirst for speed and freedom. But the question arises, which motorcycle to buy and where. Many experts recommend that beginners pay attention to Yamaha motorcycles. Compared to their predecessors, they have significantly improved in design and technical characteristics. I recommend buying a motorcycle in Moscow and the Moscow region at the Kvadrostil store. There are low prices, from 250 thousand rubles, and high-quality service. All models are covered by a factory warranty.

Heavy motorcycles were held in special esteem in the Soviet Union. They were produced only on 2, and in Kyiv - “Dnepr”. They are, of course, similar, but there are still many differences.

The popularity of such transport in the USSR is understandable. Firstly, motorcycles with sidecars were cheaper and more accessible than any car; secondly, they are quite powerful, capable of carrying three people, plus cargo; thirdly, they could be used all year round; fourthly, they often overcame off-road conditions better than some cars.

Mostly heavy motorcycles were supplied to the army and police, but sometimes they went on open sale. Often they were prizes in lotteries and a well-deserved reward for leaders in production, especially in agriculture.

The MT-11 motorcycle began to be produced in the mid-80s at the Kiev Motorcycle Plant. His appearance speaks for itself: he is stocky, bulky, and even in appearance he seems heavy (his weight is 330 kilograms). At first glance, it is clear that this technique is not for weaklings.

The MT-11 Dnepr has a strong double frame, a telescopic fork with double-sided shock absorbers. The rear suspension is wishbone with springs. Wheels – size 19. On the sides there are long silencers. The brakes are drum brakes, and the stroller has its own.

The motorcycle has a traditional 4-stroke air-cooled carburetor engine; 2 cylinders are located oppositely. Engine capacity – 650 cubic meters. Power – 36 horsepower, which is more powerful than the first Zaporozhets. The transmission is a classic 4-speed with reverse gear.

The engine is started traditionally - with a kick starter. His conversation is serious and his character is evident. When moving, the motorcycle pulls slightly to the right because of the sidecar. Gear shifting occurs clearly. The brakes are quite effective, but not for adrenaline. Still, it’s better to drive it slowly and sedately. Although the maximum speed is quite sufficient - 125 km/h.

During Perestroika, the MT-11 Dnepr motorcycle was freely sold throughout the country. But even then, the technical requirements for motorcycles increased greatly, while production technologies remained the same. Therefore, with the advent of the 90s, the demand for the products of the Kyiv Motorcycle Plant fell.

In 1992, production of model 11 was discontinued. But these motorcycles are still in use in the Russian outback, often passed down from father to son, which once again proves the durability and reliability of Soviet technology.

I suggest watching a video review of the Dnepr motorcycle:

Popular models and their technical characteristics

The basis for the creation of the Dnepr motorcycle plant was an armored tank plant. The motor vehicles produced were not very maneuverable, but were popular among citizens. During the existence of the enterprise, various modifications of Dnepr motorcycles were produced.

The first Dnepr motorcycles appeared in 1967. The K-650 model was equipped with a powerful 650 cc engine, and thanks to the good sales dynamics of the motorcycle, its widespread production was established.

Dnepr K-650

The beginning of the 70s was marked by the release of modifications MT-9 and MT-10 . Their seats had modernized shapes, the fuel tanks and gearbox were improved.

Dnepr M-9

Since 1976, the Kiev Motorcycle Plant began producing a limited version of the MT-10 with chrome parts, which is still popular among connoisseurs of Soviet technology. This modification has become faster (up to 130 km/h), while providing reliable traction even in winter thanks to powerful studded wheels.

Review and technical characteristics of Dnepr MT 10

Dnepr MT 10 belongs to the class of heavy motorcycles, which are designed to transport 2 passengers or any cargo with a total weight of up to 260 kg. Despite its impressive weight, the model is quite agile and behaves well on various types of road surfaces, be it smooth asphalt or a bad country road.

Despite the fact that the Dnepr MT 10 motorcycle model was released in 1974, the equipment is still popular among fans of customization and restoration. One of the most common improvements to equipment is increasing the maximum speed and changing the appearance of the motorcycle. As a rule, the tuning master does not touch the engine and frame.

Tuning options

Due to the closure of the Kyiv Motorcycle Plant, the modernization and modification of this motorcycle equipment has been suspended. In this regard, all improvements have to be done with your own hands or contact private specialists.

Tuning areas

The exhaust system, front fork, roll bar, footrest, and windshield are most in need of replacement. Forks, footrests and other body parts are replaced with chrome-plated counterparts.

When the exhaust system is modernized, they often install nickel-plated elbows and a direct-flow muffler. Such replacements will improve engine performance and make it sound better. Some motorcyclists, instead of reverse gear, provide the device with an additional gear in order to increase the dynamics of the motorcycle.

In the video below you can see step-by-step instructions for converting a standard gearbox into a five-speed one:

The ignition system requires modification. For this purpose, the motor vehicle is equipped with an electric starter for automatic engine start and contactless ignition. The most effective effect will be replacing the engine with a new, more powerful one. Such changes will cost a significant amount because the new engine comes with additional parts and equipment.

How much does the engine from a Ural motorcycle weigh?

The engine capacity is 750 cubic centimeters. If we talk about the gearbox, it is a four-speed one and has a reverse gear. The rear wheel has a cardan drive. The weight of the Ural motorcycle engine determines the weight of the entire machine; on average, motorcycles weigh 300 kg.

What is the difference between the Ural motorcycle and the Dnepr, which is better?

The external differences of these Ural Dnepr motorcycles are flat round fenders, teardrop-shaped flattened tanks, single panel dashboards, a double box separate from the headlight, separate from the headlight, wheel hub, spokes are not symmetrical, spokes of different lengths are symmetrical, valve covers on the cylinders are rounded flat, more square , manufacturer Irbit Kyiv. In 1939-1940, partly based on the R-71, an overhead valve engine was built, and this is how the R-75 was built, which went down in history as the BMW Sahara.

BRIEF DESCRIPTION OF THE DEVICE AND OPERATION OF MOTORCYCLE COMPONENTS, THEIR REGULATION AND MAINTENANCE

MOTORCYCLE DNEPR-11. ENGINE

The engine (Fig. 5, 6, 7) in terms of design features and technical indicators belongs to the category of forced road-type motorcycle engines.

The horizontal arrangement of the cylinders ensures good cooling and balancing of the crank mechanism. Each cylinder has a separate carburetor, which improves starting and increases engine power.

crank mechanism

The crank mechanism consists of a crankshaft with connecting rods, pistons with piston rings and piston pins, a crankcase and two cylinder heads.

Crankshaft. The double-bearing crankshaft is cast from high-strength cast iron. It has two elbows located in the same plane at an angle of 180°, and consists of a front and rear axle, a cheek and two crankpins.

The crankshaft is installed in the engine crankcase on two bearings 30 (Fig. 6) and 39. At the front end of the crankshaft, drive gear 4 of the distribution mechanism and a centrifuge are mounted, and on the conical part of the rear end - flywheel 22.

The direction of rotation of the engine crankshaft (when viewed from the front) is right.

Under normal operating conditions, the crankshaft with connecting rod bearings has a significant service life. However, when overhauling the engine, it is recommended to replace the connecting rod bearing shells. This protects the crankshaft connecting rod journals from premature wear.

Connecting rods assembled with liners. Connecting rods are steel, forged, I-section. A bronze bushing with a precisely made hole is pressed into the upper head of the connecting rod to ensure proper seating of the piston pin. The lower head of the connecting rod is asymmetrical, detachable, with thin-walled interchangeable liners. For proper installation of the connecting rods on the crankshaft, the connecting rod rods are equipped with protrusions that must be directed outward relative to the crankshaft cheek (for the right connecting rod, the protrusion is directed towards the flywheel, for the left - towards the centrifuge).

The connecting rod caps are not interchangeable. The connecting rod bolt nuts are tightened and secured.

Piston, piston rings and piston pins

. Piston 15 (Fig. 5) of the engine consists of a head, skirt and bosses. The piston has four grooves in which the piston rings are installed.

The two upper rings 14 (compression) create the necessary tightness in the cylinder and prevent the breakthrough of gases from the combustion chamber into the engine crankcase. Two lower rings 13

(oil scraper) are used to remove excess oil from the cylinder walls.

A steel oil scraper ring is installed in the third groove of the piston, consisting of four elements: two steel disks, an axial and radial expander.

A cast iron oil scraper ring is installed in the lower groove.

The axis of the hole for the piston pin is shifted by 1.5 mm from the diametrical plane of the piston, due to which the piston moves smoothly, without shocks, within the gap between the piston skirt and the cylinder walls when changing the direction of movement at top dead center. There is an arrow on the bottom of the piston indicating the correct location of the piston in the cylinder; During installation, the arrow must point forward on both pistons, i.e. towards the centrifuge.

The piston compression rings are made of special cast iron and have straight locks. The gap in the ring locks when installed in the cylinder should be within 0.25-0.5 mm.

When installing cylinders on pistons, the compression rings must be turned in different directions with locks to reduce the passage of gases.

Piston 16 (Fig. 7) is connected to the connecting rod by a floating pin, the axial displacement of which is limited by two spring retaining rings 17 inserted into the annular recesses of the piston bosses.

Carter. Crankcase 3 cast from aluminum alloy (Fig. 5) is the main body part of the engine.

Cylinders with heads and auxiliary mechanisms are installed and secured on the crankcase. In addition, the crankcase serves as an oil reservoir. The crankshaft and camshaft rotate inside the crankcase, the distribution gear box is located in the front part, and the generator is located at the top. The bottom of the crankcase is closed with a stamped pan 10. A sealing gasket 11 is installed between the crankcase and the pan.

During engine operation, part of the working mixture and exhaust gases breaks into the crankcase through the gaps of the piston rings. Besides,

When the pistons move to bottom dead center, the gases in the crankcase cavity are compressed, and under pressure, oil can flow out from the joints of the crankcase with the covers and through the seals. To avoid this, forced crankcase ventilation is used.

To connect the internal cavity of the crankcase to the atmosphere when the pistons move down and to isolate it from the atmosphere when the pistons move up, a breather 15 is installed (Fig. 6), which is located in the central hole of the cover 40 of the distribution gear box.

The gases escaping from the crankcase through the breather contain water vapor, which is why, during winter operation, an ice plug may form in the rubber tube connecting the breather to the air filter, preventing the gases from escaping from the crankcase. This may cause oil to leak through the seals. Therefore, it is recommended to remove the rubber tube when operating in winter at temperatures of 0°C and below.

Cylinders

. The engine has identical, interchangeable, bimetallic cylinders 6 (Fig. 7). The cylinder is an aluminum jacket with a cast iron sleeve. The lower part of the cylinder is equipped with a flange with holes passing through all the ribs for anchor pins for attaching cylinders and cylinder heads to the crankcase. The upper part of the cylinder has an annular collar that fits into the bore of the head.

A sealing gasket 4 is installed between the cylinder and the head.

Cylinder heads. The 3 and 12 cylinder heads are made of aluminum alloy with fins on the outer surface that increase the cooling surface. The combustion chamber of the head has a hemispherical shape. On the head, on the side opposite the combustion chamber, there are four brackets, in the holes of which rocker arms are attached. At the top there is a threaded hole for the spark plug.

Caring for the crank mechanism

During daily maintenance, you should clean the crankcase, cylinders and cylinder heads from dirt and dust, paying attention to the cleanliness of the fins (fins clogged with dirt impair engine cooling), and ensure that there is no oil leakage in the engine crankcase cavity.

If the tightness is broken due to improper installation or destruction of paper or rubber gaskets, oil seals, air leaks and the pressure in the engine crankcase increases, which leads not only to oil leakage at the connector points and through the oil seals, but also to premature contamination of the oil and increased wear of parts engine.

After 10,000 km, it is necessary to clean the combustion chambers of the cylinder heads, pistons, piston rings and valves from carbon deposits. If there is carbon deposits in the engine, detonation knocks may occur, shortening the life of the engine.

If engine oil consumption exceeds 0.25 1 per 100 km, the piston rings must be replaced.

How many ticks does the Dnieper have?

The external differences of these Ural Dnepr motorcycles are flat round fenders, teardrop-shaped flattened tanks, single panel dashboards, a double box separate from the headlight, separate from the headlight, wheel hub, spokes are not symmetrical, spokes of different lengths are symmetrical, valve covers on the cylinders are rounded flat, more square , manufacturer Irbit Kyiv. The wheel served as the impetus for the creation of the bicycle in 1817, then in 1869 a steam engine was installed on the bicycle and the result was a moped with a reserve of fuel in a special trunk, coal or firewood.
