Snowmobile test Russian Mechanics Buran

History of the Buran snowmobile

The first RMZ engine

A power unit from IZH-Jupiter-3 was installed on board the Buran. However, the engine from the motorcycle did not provide enough power, so it was decided to create a new engine. This is how the first model RMZ-640 appeared, which has undergone more than one modification during its existence. To this day, RM engineers use this engine in their equipment.

Aircraft engine assembly plant transforms into leading snowmobile manufacturer

Previously, the enterprise was called “Rybinsk Motors” and was engaged in the production of engines for aircraft, but the management did not want to stop there. Design engineers were tasked with creating equipment that would be accessible to a wide range of buyers and in demand.

The main specialization of the enterprise is the development and production of snowmobile equipment. However, the Rybinsk plant also produces several models of ATVs and motorized towing vehicles. Among residents of the northern regions of our country, RM products are in great demand. The quality of domestic snowmobiles can compete with their foreign counterparts. “Russian Mechanics” is not just a workshop for assembling Chinese equipment, but a full-fledged company that controls production at all stages, starting with development.

Description and technical characteristics of the snowmobile "Buran"

The Buran snowmobile is an old, time-tested snowmobile track. It is chosen by hunters and fishermen due to its cost, as well as good maneuverability and the ability to pull large loads. The all-terrain vehicle has become a real legend of domestic all-terrain vehicle production, and now, more than forty years after the start of production, it continues to be produced. The model has more than forty years of history, during which it has undergone many changes. Over the entire period, more than four hundred units of equipment rolled off the plant’s assembly line.

This snowmobile track, in accordance with the manufacturer’s classic design, has one guide ski. New models of the RM “Buran” snowmobile are distinguished by their modern design and smooth shapes. However, these are still the same “workhorses”, capable of pulling loaded sleds weighing up to half a ton.

The modern lineup includes machines:

• "Buran A/AE";
• "Buran AD/ADE";
• "Buran 4T/4TD".

Modification A/AE: main characteristics

The Buran A snowbike received a two-stroke engine with two cylinders and a power of 34 horsepower. The motor is cooled using air. The truck has good traction and is capable of reaching speeds of up to 60 km/h.

This model does not have an electric starter.

The next version of the all-terrain vehicle has a modified hood. The manufacturer used injection molded plastic as the basis. The material is impact-resistant and can withstand severe frosts. Unlike its predecessor, it has an electric starter. A model with a long platform will weigh a little more.

How is the second model different?

The technical parameters of this snowmobile track are practically no different from the previous one. Both modifications have an electric starter, a long platform and a ski base on board.

New four-stroke Buran

The latest modification of the Buran snowmobile has received radically different characteristics. This is not just a reliable, but also an economical tractor.

Thanks to the installation of a four-stroke engine, the manufacturer managed to reduce fuel consumption. At the same time, the model is distinguished by comfort and high cross-country ability. The main difference between the 4T and 4TD modifications is that in the second case the track has an extended platform.

• headlight mode switch.

Some control elements are missing in the shortened model. In addition to the above, the 4TD version provides a toggle switch for the spotlight, as well as a power unit failure indicator.

Engine and fuel

The Buran has a two-stroke engine. The successful design allowed it to exist for almost four decades and reach the present day without any major alterations. Runs on an oil-fuel mixture. Gasoline is poured along with oil. There is no separate lubrication system provided here.

Access to the engine compartment is very convenient. Everything is very simple. You just need to open the hood of the snowmobile, and you can reach any unit. The engine compartment is very large. It should be noted that the hood is attached very conveniently and is secured with two rubber bands. On its upper part there are wide air intakes. They serve for good air cooling of the engine, which produces 34 horsepower. The maximum speed is about 60-70 km/h. "Buran" has a disc brake system.

The fuel tank is quite large and located at the front. If you compare it with a car, it is in the place of the radiator. Capacity - 35 liters. The Buran snowmobile, whose fuel consumption is about 15-20 liters per 100 km, can be called a very voracious unit. Gasoline is used AI-92. Filled with oil. Diluted 1:50 - 1 liter of oil for 50 liters of gasoline. It is used in the same way as in imported chainsaws. The hatch for refueling the snowmobile is located in front, under the headlight.

Breakdowns and repair features

In the operating manual for this machine, owners will find a detailed list of track faults, their descriptions, as well as recommendations for elimination.

Some faults:

Appearance and tuning of the snowmobile

This snowbike got its name in honor of a snowstorm, which is why its hood is invariably white. The vehicle is in great demand due to its relatively low cost, cross-country ability and traction properties. The price of a new snowmobile version 4T from an official dealer is 355 thousand rubles. A model with a long platform will cost 20 thousand more.

On the Internet you can find a lot of positive feedback from owners, look at reviews and test drives. In addition, Buran lends itself well to modernization. Of course, it won’t be possible to turn a budget utility vehicle into a racing truck, but it is quite possible to improve its performance characteristics.

To reduce noise levels, sealed bearings are installed. The Safari regulator, which is installed from the factory on snowmobiles of the Taiga line, helps to increase the number of engine revolutions. If you install an on-board computer, the all-terrain vehicle will look no worse than its expensive foreign counterparts.

Full tuning

There are a number of companies that offer assembled kits for the complete modernization of this all-terrain vehicle. However, each owner can assemble such a set himself and save money. Standard kit includes:

• Honda engine (22 hp, 2 cylinders);
• Arctic regulator with four positions;
• Battery with a capacity of 24 ampere-hours;
• fastening cable for the power unit;
• soundproofed hood;
• bumper bumper.

In addition, you can install a lightweight spring on the brake mechanism. This will make the stopping process more comfortable.

"Buran AD and ADE"

Reviews about the long-wheelbase Buran snowmobile say that thanks to the elongated frame, the supporting surface area has become larger, and therefore the cross-country ability has become higher. This is especially important when operating the snowmobile on loose and deep snow. In terms of equipment, the model has nothing new:

1. 2-cylinder 2-stroke engine.
2. Volume – 635 cm3.
3. Power – 38 hp

Thanks to the lengthening of the base, Buran AD received a loading platform. The package includes a hitch capable of towing a trailer weighing up to 500 kg. The standard kit includes a rotating spotlight that illuminates areas without light.

There are interesting reviews about such a model as the Buran ADE snowmobile. For example, it is noted that the machine shows excellent maneuverability and long-term operation without breakdowns. On the other hand, you often have to change the chain, which is not very convenient; in addition, the motor is too noisy. From a technical point of view, this model has an extended frame, electric start, a cargo area and a cornering headlight.
