Technical characteristics of the alpha 72 cc moped engine

Engine Alpha 72 cc

Let's start, first of all, with the heart of any technology, its engine. The engine on the Alpha 72cc is four-stroke, which is already an advantage, and its cooling occurs by getting air onto the surface or, in other words, by air. As for the engine capacity that the Alpha moped can “boast” of, it is, as the name suggests, 72 cubic meters. cm. Despite such a small volume, this model develops enormous speed and incredible power . In a process involving repairs aimed at modernizing the power unit, it is possible to significantly add power.

If we convert the standard power that the Alpha moped can pull into hp, it will be 5 horses. And its maximum speed does not exceed 7.5-8 thousand rpm.

This engine starts with an electric starter, but there is another option. Manufacturers made sure that the user was able to start the Alpha 72 cc even if the starter was damaged. For this purpose, there is a kick starter, which makes it possible to start it manually.

The transmission of the Alfa 72 cc is 4-speed and manual. She sets it in motion without much difficulty.

Maintenance and repair of moped chassis

Repair of the Alpha moped (72 cc), caused by major breakdowns, can be completely eliminated by carrying out regular preventive replacement of those parts that have obvious signs of wear. The chain on a moped should be replaced after each season or after 2000 km. The chain stretches very significantly, which increases wear on both sprockets. Due to the chain breaking at high speed, a situation with sudden locking of the rear wheel is possible, which can lead to a dangerous fall, injuries and even greater damage to the motorcycle. On the road, this situation can cause destruction of the tension elements of the rear wheel, severe deformation or complete destruction of the tension mounting sockets. Artificially shortening the chain contributes to rapid wear of both sprockets. After 7,000 km, tires completely lose their tread texture and traction. They need to be changed after 2-3 seasons of use. The clutch, fuel supply and front wheel brake drum control cables should be shortened after each season of operation due to their stretching. The rubber bands in the brake drums gradually deform, which increases wheel play. It is also better to change them after each season of use.

Features of the Alpha moped

Alpha 72 cube has its own characteristics. In particular, they have the following properties.

Shock absorbers

Among the features of the Alfa, shock absorbers can also be highlighted. They are hydraulic. This makes it possible to quickly maneuver in difficult conditions without fear of consequences. The excellent shock absorbers that this model has, as well as a strong frame, the correct wheel diameter and much more - this is the ability to pass through holes and potholes, for example, on rural country roads. Repairs, even after going through the worst off-road conditions, will only be required for decorative inserts.

Interestingly, the Alpha moped provides another unique opportunity. It is appreciated by many handymen. The “homemade” craftsmen manage to install even shock absorbers from Russian Minsk or Voskhod motorcycles on this moped when repairs are being carried out. It is clear that this way you can save a lot on spare parts, and in some cases, increase the cross-country ability of the Alpha moped.

Fuel tank

The Alfa's fuel tank is not so large, but this can be easily explained. The fact is that these 4 liters are enough for 200 km and therefore there was no need to equip a light moped with a large tank.

As for the contents of the tank, you can fill it with regular Russian 95 gasoline.

The carrying capacity of this Alpha model is also admirable. This moped can easily pull 120 kg. In other words, if two adult men sit on a moped, it will go without any problems. According to some rural residents who own a moped of this model, it copes well even with slush and dirty roads.

In a word, the cross-country ability of the Alpha 72 cc is at the highest level. This moped is ideal for trips to the country or to the lake.

Design

It is an example to follow and the design of this brainchild of the Chinese motorcycle industry. You admire a moped as if it were a real motorcycle. In addition, the Alpha 72 muffler is of particular beauty, made in a special shape and emitting pleasant sporty notes. The feet of the owner of the Alpha 72 cube will stand on shiny stands. In a word, a real classic of the genre, only instead of a real bike - a moped.

The instrument panel is also good looking. It includes a speedometer and various warning lights. They are very useful when driving, as they notify the driver about which light is currently on - high or low, which turn signal is activated, and so on.

The rear view mirrors are a special design feature. They are beautiful and highlight the beauty of our moped.

Behind the driver’s back, as expected, there is space for a trunk. Incredibly comfortable backrest for the passenger, stylish and practical.

Safety

As for safety while driving, there are some advantages here too. Side arches that do not deform when the moped falls in an accident (they practically do not require repairs). They are all metal, made from durable pipes.

Summary

The Alpha moped will be an excellent choice for a person who loves to spend time outdoors, looking for the pleasure of fishing or other hobbies. On the other hand, this moped, the price of which can surprise, can also be an excellent solution for urban leisure. This moped can even be used as a business tool. Comfortable and maneuverable, in a large metropolis, such as Moscow, for example, this moped will be an excellent type of equipment on which you can pass through the most gigantic traffic jams and traffic jams without any problems.

Additional tool

In the standard set of tools for the Alpha moped there is no special key to adjust the gas distribution system of the moped. It is customary to contact specialists with this question. If you plan to thoroughly maintain your moped, you should get one. Also on the list of useful wrenches and accessories is an alternator puller and a castle wrench for unscrewing the clutch castle nut.

When handling any equipment, production culture is important. If you do not carry out all the work with a hammer and chisel, the moped will serve faithfully for many years.

Video review of the Alpha 72cc moped

The Alfa moped has its own body kit, front and rear shock absorbers, a 4-stroke engine, in general the characteristics are impressive, they will be discussed in more detail below.

The technical characteristics of Alpha mopeds are impressive and constitute serious competition in the market for companies selling mopeds. Perhaps we should start with the engine.

The engine has 4 strokes, like a passenger car, and is air cooled. The engine capacity is 72 cubic centimeters, but with such small volumes it develops quite a lot of power.

The engine is powered by an electric starter, but if it malfunctions (this happens very rarely on a moped), you can use a kick starter, that is, start the moped manually. We started it up and now we can safely drive, a four-speed manual transmission will set us in motion.

There is a chain running from the engine to the wheel, not a driveshaft. The moped is one meter long, one meter high and half a meter wide. Its own weight (without any bells and whistles) is eighty-one kilograms. Quite light weight for such a moped. The front wheel is seventeen inches, the rear is the same, but the rear has more volume than the front. The brakes are activated by pressing the levers on the steering wheel. The brakes are of a drum design.

four-stroke air-cooled

Patency

The moped has front hydraulic shock absorbers. 17-size alloy wheels provide maneuverability and at the same time stability on the road. You can ride such a moped both in the countryside and around the city, both on road and off-road.

Economy and endurance

The fuel tank is only four liters and this can be easily explained by the fact that fuel consumption per hundred kilometers does not exceed 2 liters! You can fill in gasoline of the ninety-second brand, but those who are richer or just want to take care of their iron horse can fill in the ninety-fifth. The moped's carrying capacity is quite high: one hundred and twenty kilograms. Two are easy to get lucky!

Appearance of Alpha RX

Alpha RX is an updated version of the previous classic moped. The new moped has become more interesting and elegant in appearance. The exterior has a modern look which I liked. The tank has been updated, a two-level seat has been installed - the passenger is now slightly higher than the driver. The passenger's visibility is now better. The wings are now made of plastic, but only the front wing is painted. This already saves the wings from corrosion.

The headlight became larger than that of the classic Alpha, a serious halogen lamp was installed, and the light became brighter. The rear shock absorbers have become more advanced in shape. The motorcycle is also equipped with serious lighting equipment - front and rear lights, turn signals with sound, high and low beams, a signal and a brake light.

Very easy to use. Repair is possible with a minimum set of tools, but you will have to stock up on additional open-end wrenches: 9, 11 and 15.

It comes in two versions for sale: with a 72 cc and 110 cc engine. But lately they have been supplied partially unserviceable with a 50cc piston that will need to be upgraded. These versions of the models are called Alpha 7 and Alpha 11.

These numbers are deciphered as follows:

• 7 is an Alpha, which after modification will become a 72 cc model.
• 11 is the Alpha, which will become a 110 cc model.

Initially, these models cost like “fifty dollars” and they will not be able to drive. In any case, they will have to be modified. But according to the documents, they are like mopeds with 49.9 cubic meters and there is no need to register them with the traffic police. The only thing you need is a driver's license of any category.

Specifications

The new Alpha 110 cc mopeds are equipped with a four-stroke single-cylinder gasoline unit. Its power is 3 kW (5 hp). The Alpha 110cc moped engine is capable of providing acceptable acceleration and traction characteristics (0-100 km/h:

15 seconds, load capacity: 120 kg).

One cylinder can withstand loads of up to 7500 rpm. The 4-speed manual transmission ensures smooth acceleration. Despite the engine size, fuel consumption is only 2 liters per 100 km.

You can start the moped in one of two ways:

The suspension is designed for use in areas with a lot of bumps. The rear wheel differs from the front in having a wider tire (2.75 inches versus 2.50 inches). The brake system consists of two drums, each of which is located in the central part of each of the wheels. It is impossible to separate the discs from the hubs, since the wheel does not have removable spokes.

Vibration damage

Some moped breakdowns may be associated with the destruction of its load-bearing elements. The plastic front wing on the Alpha lasts longer than the metal one, since it is less susceptible to the negative effects of vibration. Engine mounting points on the frame can also be damaged due to vibration. To avoid this, you need to weld wide washers onto them. After 2-3 seasons, the battery loses up to 50% of its capacity, so its regular replacement is also advisable. Electrical clutch and turn signal sensors must operate normally. Both safety while driving and correct control of gear shifting depend on them. The standard rear shock absorbers on the Alfa wear out, which can lead to unwanted friction between the rear wheel and the inner surface of the rear wing. There are luxury rear shock absorber options for the Alfa that allow you to put fat tires on the rear wheels, as they can help raise the rear of the bike a little. If you handle fasteners with care, serious problems with the repair of this moped are unlikely.

Owner reviews

Considering the Alpha moped as the main transport, it is advisable to read the owners’ reviews in advance. We analyzed the comments from the owners, which you can read below:

Analogs

Comparison with analogues of the Alpha moped led to the identification of competitive models. It turned out that there is only one model that can lure potential buyers to itself: Soul Lux S. The technical characteristics are similar. The difference lies in the dimensions (the competitor is 2 cm wider and 6 cm longer) and the presence of a large windshield. The Soul Lux S is $50 more expensive, and the reason for paying extra is the windshield.

Setting TDC on Alpha

To start adjusting the valves on the Alpha moped, you need to set the top dead center. To do this, remove two covers on the rotor cover. Rotate the rotor until the T mark appears.

To accurately control this process, you need to remove the timing sprocket cover. To do this, on the opposite side you need to unscrew the clamping bolt, which can be unscrewed with a 10mm wrench. Remove the timing chain sprocket cover carefully so as not to damage the gasket.

The star has a mark in the form of a dot. It should be aligned with the mark on the head body.

To easily turn the engine mechanisms, I unscrewed the spark plug, reducing the compression to nothing.

Now you can begin adjusting the valves on the engine.

Photo report: Replacing the rear chain of an Alpha moped

Torque chain transmission is always a problem. But low cost, ease of maintenance, coupled with low weight, and for a motorcycle - weight is a very significant parameter - outweigh all the disadvantages and the chain drive of the rear wheel, just like many years ago, is dominant in the motorcycle industry. And we are unlikely to get away from this in the coming decades.

As already said: the chain is always a problem. The infection is spreading and nothing can be done about it. And if only it drags on, it begins to eat the teeth of the stars and if it is not replaced with a new one in time, then it will literally eat the stars in one season.

Without going into theory, let's consider a classic case: the chain has stretched and requires urgent replacement. If you look closely at the picture, you will see that the chain rollers do not fit into the sprocket teeth. As a result, the chain rollers hit the sprocket teeth and eat it up literally in one season.

Alfa moped/motorcycle: best, worst or controversial?

Since the popularity of mopeds has lasted for several generations, today on the streets of Russian and Ukrainian cities you can still see the old “Riga” and “Verkhovyna”, which were produced back in the days of the Soviet Union - surprisingly, they continue to function properly.

However, Alpha and Delta, which had already become famous, surpassed even Verkhovyna and Karpaty. There have been, are and will be debates about them forever. One half of the owners hate this motorcycle, the other considers it one of the most flexible and reliable. Let's try to figure it out.

Types and modifications

There are many different types of Alpha and Delta and they all differ in wheel design, tank, color - in general, all sorts of little things. The only really important feature of this moped is the engine. There are such modifications of motors according to the cylinder volume criterion:

Here is the famous video (500 thousand views - half a million hopes of mopedists) about the two-cylinder Alpha:

Each of the above types of engines (we are not considering the 2-cylinder one, since it does not exist for sale) exists in the following two modifications based on the type of gearbox:

The Delta moped is the same as the Alpha. All characteristics are similar. Anyone who seeks deep difference is doomed to failure, since there are no differences. The only differences are external. The Delta is more rare, more rustic, it has a square, somewhat dated headlight, and a rectangular speedometer, the tank is located as part of the frame, which allows you to use the free space for the pannier.

Alpha/Delta engine

The Alpha moped, unlike the Delta, is equipped with a large motorcycle tank, a tachometer, and round (occasionally a pair of round) motorcycle headlights. In other words, the Alpha is a little more motorcycle-like in appearance, because the Delta (even with a 125 cc engine) is a doomed moped.

The Alpha 110 moped is the most popular model; all motorcycle stores in Russia, Ukraine, Belarus, and Kazakhstan are filled with spare parts for this particular motorcycle. Its engine costs 10,000 rubles. And this is the price of a new one! With very careful maintenance, it can travel 35 thousand kilometers without failures. Now tell me, is there a more profitable motor on the planet? 3.5 kilometers of engine life costs exactly 1 ruble! Is the motor broken? Throw it away, buy a new one and you have a new alpha again. Yes, this is exactly why everyone loves this moped. There are about 2 dozen factories producing Alpha engines. Zongshen is considered the best.

There are myths, and sellers are very fond of misleading them, that there is a Japanese engine for Alpha. It is not true. The last Japanese engine for this technique was created in the late 80s and was no longer produced.

Lacks low end and traction power

You will have to disassemble the motor and change the technical specifications. Alfa moped engine tuning is provided with components of different prices and quality. A motor of this configuration is an exact copy of a Honda motor that has been produced for many years. There are clubs for moped lovers with this engine all over the world. Road races, enduro and off-road races are held. And, as a rule, where there is serious sport, there is civilian tuning. Forged piston and connecting rod, four-valve head with Ducati-style desmodromic mechanism, dry clutch, water cooling. The injection system is from Yoshimura... But since we are now talking about an Alpha moped, the price of which in the store is less than the cost of any of the listed components, our tuning option is more modest.

Alpha engine tuning

Engine tuning can be immediate aggregate or unit and stage-by-stage. On sale you can find engines with the same method of mounting to the frame, but with a volume of 110 cc, 125 cc or 150 cc. An increase in engine capacity will entail the need to register with the traffic police, but this is an organizational issue. The technical side will be as follows: the electrical wiring remains the same, a larger engine will require a different carburetor and a different exhaust pipe. Most likely, they will be found in the same place as the motor itself.

Characteristics

The Alpha 110 motorcycle can be used both for riding on city streets and for long trips in the countryside.

Alpha. 2018 model

The latest Alpha model, which left the factory in 2022, received a number of updates:

Officially, Alpha 110 belongs to scooters. But despite this, its appearance is more suitable for a motorcycle. Among the distinctive design features of the Alpha 110 moped are:

Design

The Alpha moped (110 cc), although it belongs to the class of scooters, looks very much like a light motorcycle. The main distinguishing features of this Chinese technology are the presence of mirrors, increased wheel diameter, and a large front fork. It has many elements made of chromed metal. The Alpha moped (110 cubic meters) has very impressive dimensions for its class and an original exterior. As a nice bonus, it is equipped with a muffler with an interesting configuration. The latter, judging by the reviews, makes a very unique sound when the engine is running. Another innovation is the elegant footrests. Among other interesting additions that the Alpha moped (110 cc) is equipped with, experts note a beautiful instrument panel equipped with a lot of indicators, a space for a trunk, which provides additional safety for the driver, and side arches made of metal.

Fuel tank

It is worth recognizing that the volume of the fuel tank of the Alpha 110 moped is not very large - the maximum amount of fuel it can hold is four liters.

You should know! These are the passport data, but for unknown reasons the tank holds 6.5 liters. Apparently, this restriction is intended to prevent the driver from overfilling fuel when cornering while leaning.

At the same time, due to the fact that the maximum gasoline consumption per 100 kilometers is two liters, the fuel tank can be characterized as an economical solution by the manufacturer. This fuel tank can only be filled with gasoline of the AI-92 or AI-95 series.

Tests were carried out and 98 and even 76 gasoline were filled. From the AI-76, the carburetor began to malfunction, the float chamber became clogged and the motorcycle stalled. The equipment ran well on the AI-98, but the cylinder overheated too much.

Advantages of the model

First of all, it is worth noting that some characteristics of the Alpha 110 moped exceed the distinctive features of two-seater mopeds. For example, this motorcycle is equipped with a comfortable seat for a passenger and a capacious trunk. The seat itself is quite comfortable, and, moreover, even two adult men can fit on it. There have been cases when this moped carried three people. This is unsafe and should never be done, but the fact remains.

The Alpha moped climbs any hill without any problems

Also among the advantages of the moped is that you can make steep climbs on it without much difficulty - this is possible thanks to the four-speed gearbox. An experienced driver is quite capable of achieving maximum performance from a moped engine.

It is also worth noting the electric starter, which in case of unexpected unpleasant situations on the road allows you to start the moped - it is quite high quality.

The main advantages of a moped also include an increased level of comfort while moving. Thanks to this, the driver is able to make even particularly long trips. If we talk about the driver's seat itself, its seating position is quite high and comfortable, and the footrests are located exactly where needed. The steering wheel has a delicate smooth bend.

It is worth talking separately about the dashboard - it is quite informative, and due to the large size of the speedometer and tachometer, a quick reading of their indicators is possible even during bad weather conditions.
