Tire is an important part so that it is said that the limit of the performance of modern racing bike is tire. Even if the performance of the engine and brakes goes up, there is no point if the tire can not accept it.

And it is the work of the rider to bring out the performance of such a tire by 100%. If it runs normally, it is this tire where only the middle decreases, but what kind of reduction method is the tire used by the world's fastest racer?Tokyo Motorcycle Show 2010At the Bridgestone booth, the tires actually used at the road race world championship were exhibited.
