Buran SB-640AD powerful snowmobile with a cargo platform

The Buran A snowmobile is a real long-liver in the market of domestic winter all-terrain vehicles. It began to be produced back in 1971. At first, snowmobiles were made only for border guards, foresters and virgin snow explorers. But the equipment turned out to be so convenient that soon hunters, fishermen, and lovers of active winter recreation began to buy it for personal needs. The advantages of the model are that it is maximally protected from rollovers, and is also capable of carrying large loads. Even at a temperature of -30 degrees, the snowmobile remains on the move and does not stall.

Design and main mechanisms

Buran A/AE has a long history, during which the main parameters have remained unchanged. But the design has undergone modifications more than once, striving for modern trends. A couple of years ago, the manufacturer made changes to the appearance of the hood, as well as to its mounting scheme. Now, when tilted, full access to all necessary engine components and assemblies is provided.

The hood is made of injection molded plastic, which is highly resistant to various external influences and impacts. It has quite high strength even at very low temperatures. The level of comfort is increased due to the installation of a high two-level seat on the Buran, which has a removable backrest for the passenger.

There are two versions of the snowmobile - Buran A and Buran AE. Externally, both cars are completely identical, but the model with the letter E has an electric starter. The letter A means that the snowmobile has a short platform. Model catalog number - 110000300 and 110000300 01, respectively

Power point

The Buran A/AE snowmobile is equipped with a two-stroke, two-cylinder power plant of the RMZ-640 brand. This engine has a significantly reduced compression ratio, which allows the use of fuel of different brands - AI-92, A-76 and AI-80. Instead of regular gasoline, you can use gas condensate (gasoline) - even with it, the engine confidently develops its maximum power characteristics.

Mikuni brand float type carburetor. The diameter of each cylinder is 76 millimeters. The total working volume is 0.635 liters. The piston stroke is 70 millimeters. At the same time, the RMZ-640 motor is capable of developing a rated output power of 25 kilowatts, which translates to 34 horsepower. The unit is protected from overheating by an air cooling system, which has become standard for all winter cars.

Large traction force is achieved thanks to the large gear ratio of the final drive in the gearbox, the use of an Alpina model variator and a power plant with a fairly large maximum torque. It is worth noting that the engine develops maximum torque at low speeds. This allows you to drag a load weighing more than 250 kilograms without any difficulty.

Buran SB-640AD powerful snowmobile with a cargo platform


As part of the line of popular Buran snowmobiles with an extended track, there is the SB-640AD model, whose design and chassis of the snowmobile allows it to transport cargo not only on a trailer, but also on the loading area of ​​the snowmobile itself.
Buran AD is a new modification of the SB-640MD, for which the Buran Arktika was the base model. The technical indicators and equipment of these snowmobiles coincide in many respects.

The nominal operating mode of the engine is provided by an automatic transmission of two versions. Brakes - disc and hydraulic, chain drive, 1-speed gearbox with reverse. In the basic Buran model and in subsequent models, the service life of the gearbox was increased by installing a tensioner on the chain.

The SB-640AD has a snowmobile chassis equipped with a roller balancer, which made it possible to place a platform for small loads on the snowmobile. This design solution immediately attracted the attention of fishermen and hunters. Snowmobiles are equipped with serial, powerful engines. They operate stably at low and medium speeds and are economical - the snowmobile consumes 21 liters per 100 km of heavy road.

Starting the engine is possible in two versions - manual (MA) and electric starter (ADE). The launch parameters are reflected in the configuration number and therefore the cost of the snowmobile for the AD variant is ~180,000 rubles, and for the ADE variant ~200,000 rubles.

Snowmobiles, thanks to the design of elongated tracks, have good traction when moving on loose snow on slopes of up to 20 degrees. Buran's chassis allows for reversing and turning with a radius of 8 meters.

Technical characteristics of the Buran SB-640AD :

  • Total length 2845mm
  • Length without ski 2665mm
  • Width with skis 900mm
  • Height with glass 1320mm
  • Track dimensions 3686.5x380mm
  • Dry weight 310kg
  • Gross trailer weight 500kg
  • The volume of the gas tank is 28 liters.
  • Engine PM3-640
  • Forced-air cooling
  • 2 strokes, 2 cylinders 1 carburetor
  • Cylinder diameter 76mm
  • Piston stroke 70mm
  • Volume – 635cc
  • Operating power - 34hp
  • Gasoline – AI-80
  • Speed ​​max 55 km/hour.

The SB-640AD model has a snowmobile chassis equipped with a particularly durable ski suspension, and in addition, to improve visibility in difficult conditions, in addition to the main headlight, a rotating spotlight is included in the kit. These and other ergonomic design improvements provide driver comfort and the ability to carry heavy loads in snowy terrain.

Buran SB-640AD is a reliable snowmobile with increased load capacity.

Chassis

The snowmobile has one steering ski and two rear tracks. Thanks to this, the car is not afraid of stumps, snags, bushes and tree branches that can cause damage to the chassis. The use of exactly two tracks had a positive effect on the vehicle’s maneuverability, since their total area ensures low specific pressure.

Another key point is maneuverability. With this, everything is great with Buran, since one swivel ski, combined with a fairly short longitudinal base of the equipment, allows you to maintain nimbleness in rather cramped conditions, for example, to easily go around trees in forest areas. The modernized frame, which received a front bevel in the tunnel, coupled with increased ground clearance, allows you to easily move through deep snow.

It should be emphasized that the Buran A snowmobile is very simple and unpretentious in further maintenance. Spare parts are easy to find. The machine has excellent maintainability even in field conditions far from civilization.

Buran will live forever!

Do you want to cut through the snowy expanses where even a widely advertised SUV cannot pass? Then you just need to switch to the Buran 640 snowmobile! No joke, it is the “Buran” that will go where all other models of snowmobiles with one track will bury themselves, and the dogs simply will not be able to pass. Another nice plus is that the Buran snowmobile will support your weight even on thin ice (only if you stay on it, otherwise you simply risk falling through). So in the matter of laying paths, rolling roads and ski slopes, “Buran” is simply irreplaceable!

In addition, the Buran 640 has a large carrying capacity - on its own trail it is capable of dragging a sleigh weighing a whole ton (if you move such a load well). A serviceable vehicle will start at the lowest temperatures - even on the first try (this is due to the peculiarities of its design). And, finally, this unique machine is absolutely repairable even for a driver who is not particularly knowledgeable in correcting deficiencies in snowmobiles - it can be repaired with only wrenches, a screwdriver, an ignition switch and the necessary spare parts for a Buran snowmobile (online store on our website will help you purchase them without even leaving your home).

Historical reference

The BURAN snowmobile is the first domestic snowmobile. Over four decades, the model has become the most famous brand in Russia. The snowmobile lineup consists of eight trim levels. The fundamental differences are the new design, the length of the track, the presence of a headlight and, of course, the price of the product. The reliability of Burans, their ease of maintenance, stability at low temperatures, high cross-country ability, and availability of spare parts make Buran snowmobiles a truly popular brand. The machine is indispensable for driving in forested and hard-to-reach areas due to its maneuverability. Two tracks and one support-steering ski create an original design for successfully overcoming forest off-road conditions. Burans can transport trailers weighing up to 500 kilograms. Reviews of the Buran snowmobiles confirm the popularity and demand of this veteran of the snowmobile industry. Names of snowmobile models that Russian Mechanics produced until 2008: Buran SB-640A, SB-640M, SB-640MD, SB-640 MD cat. 8 (3700) Arctic

How much does it cost and where to buy

The cost of the new Buran A/AE when purchased directly from the manufacturer will be equal to 259 thousand rubles. But delivery is carried out only in the Moscow and Yaroslavl regions. Residents of other regions should contact dealers. Their price will be more expensive, since it includes the cost of transportation from the manufacturer’s warehouses (the vehicle will cost 265-280 thousand rubles, depending on the region).

A used snowmobile costs much less - from 185 thousand rubles to 220 thousand Russian rubles. The price of a used version depends on the year of production, general technical condition and the number of kilometers traveled.
