Motorcycle racers are a special category of athletes for whom extreme sports often become the meaning of life. To drive a snarling two-wheeled car along the track at a speed of over two hundred kilometers per hour or to take part in competitions for the championship among professionals is the dream of many motorcyclists. This desire can come true only if there are technical means.

Enduro

There is a type of motorcycle sport that combines both extreme and extreme physical exertion. This is motocross on mountain trails. Such an activity is only possible for hardy, specially trained athletes, and it is associated with a unique technical base. Special motorcycles of the "enduro" class take part in competitions on high- altitude tracks, which means "restraint" in Latin.

Mountain bikes are specially tuned machines with reduced transmission ratios. Most motorcycles in this category are capable of developing up to 70 km / h, that is, three times less when compared withroad model.

In addition, mountain bikes have a number of characteristics that distinguish them from circuit racing machines. First of all, this is an increased diameter of the front wheel, as a rule, it is not less than 21 inches. Such a significant increase in comparison with the rear wheel is due to the need for super-maneuvering in mountainous conditions. A smaller diameter front wheel simply won't handle the dynamics of cornering, banking, leaning and skidding.

Specifications

Mountain bikes do not have turn signals, and there is no brake light either. The seat position is very high, and the rider almost never sits on it, he is in a standing position on the footpegs to be able to absorb the incessant jolts from below while moving over bumps and bumps.

Mountain bikes have a maximum ground clearance, otherwise the engine crankcase will inevitably collide with the ground and stones. The front fender is raised high above the wheel and is located at the junction of the horizontal bracket with the telescopic struts. Also, sports mountain bikes are never equipped with headlights and other electrical devices, as there is a high probability of damage during the race.

Producers

Companies producing mountain crossovers are few and far between, and they are mainly located in Japan. These are Suzuki, Yamaha and Honda. Almost all models are equipped with a 125-250 cc engine. cm, large cubic capacitycylinder does not make sense, excess engine power will be left without use.

Popular models

The following models are in demand on the Russian market:

• Honda XR130R.
• Suzuki Djebel 200.
• Yamaha VR250X 10.
• Yamaha PW50'10.
• Honda XR250 Baja.
• Honda CRF230.

Cost

Two-wheeled sports equipment is quite expensive if they are Japanese motorcycles of the original assembly. But the market is literally littered with relatively inexpensive Chinese-made models. The Racer company alone delivers up to six new developments every year, and they have good technical characteristics. The Chinese also produce enduro motorcycles, which, although they cannot compete with Japanese-made motorcycles, have firmly occupied their own niche.

Chinese mountain bike, the price of which is an order of magnitude lower than the Suzuki or Honda models, has its own exclusive advantages, among which, first of all, economy is noted. And since Enduros are equipped with very small fuel capacities, and gas consumption is significant, this factor is of no small importance.

The cost of mountain bikes can vary from 55 to 500 thousand rubles, depending on the model and year of manufacture. A high class car such as the Aprilia Dorsoduro 750 can be purchased for 354,000 rubles. A simpler model - "Kawasaki Versus 650" - will cost274 thousand in ruble equivalent.
