Cross-road motorcycles are off-road speed

One of the types of motorcycle sport is motocross. This is a spectacular race in sporting special bikes. The race is conducted over rough terrain. A closed circuit is built on the field and obstacles are set. Obstacles use either artificial or natural.

At first in motocross competitions participated racers on ordinary road motorcycles. But these tales they Adapted to the movement on the rough terrain on their own. They had to facilitate motorcycles. We were shooting useless parts for the competition: trunks, lights, passenger footboards and so on. Simultaneously, the suspension was modified and the thrust of the engine was increased.

And now there were cross-motorcycles. There have been evolutionary changes in the design. Initially, the steering wheel was very wide, but it was reduced, and the stroke of the pendulum and fork slightly increased. Located below the exhaust pipes the riders had to lift. In this way, their failure was prevented in the fall.

Of course, cross-bikes are not at all like road bikes. The weight of the engine was reduced, and its traction was increased. Heavy 4-stroke engines replaced the revolving, light and uncomplicated in the assembly 2-stroke. Only single-cylinder motors were manufactured. Then came the cross rubber. This nuance made it possible to radically improve the handling of the bike. The electric starter was replaced by a kickstarter, and the battery was abolished.

So, what is the design of cross-motorcycles? Innovations appeared in the 80s:

  • Now the seat seemed to float on the tank. This nuance allowed the rider on the motorcycle to comfortably carry out various movements.
  • The old drum brake was heavy and inefficient. He was replaced by a disc brake.
  • There was a progressive suspension with a mono-shock. Thanks to her, the shock absorber's work was adequate in any mode.
  • Air cooling was replaced by water cooling.

The current cross-bikes have a powerful engine, light frame and an impressive suspension stroke - from 300 mm or more. They do not have a side stop, mirrors, dashboard and light inventory. Very often they do not have an electric starter. The engines can be either push-pull or four-stroke.

Cross-country tales in traffic police do not register. After all, they do not have a certificate necessary for movement on public routes. They do not have a license plate and a PTS. To manage such a bike, you do not need to have a driving license, because it is a sports inventory.

I wonder what is the "Cross Monster 250" motorcycle (TTR 250)? He is "YAMAHA TTR 250R", and he is very popular in Russia as "IRBIS TTR 250". He does not need registration and driving license. From optics on it there is only a headlight. Equipped with a vertical motor 250 cu. See This two-wheeled all-terrain vehicle for all occasions, a bike for any roads.
