The Honda CBR250 is equipped with a water cooled inline 4 cylinder engine. The engine is inclined forward 35°. This inclination enables an improved straight intake manifold port, which allows smooth flow of air-fuel mixture gas. The gear drive system was applied to the cam shaft instead of chain drive system. The gear system is optimized for high speed operation. In order to provide smooth valve operation at high speed, the engine has lower shim design. Also, carbon hardened connecting rods used to reduce friction loss.
