CYLINDER-PISTON KIT FOR MONTESA-HRC 300cc 4RT.
High quality product. The increase in displacement considerably increases the torque and power. The engine is fuller from low revs without being violent. The rise in revolution is faster and the power at high rpm is considerable.
In order to mount the 300cc cylinder it will be necessary to retouch the crankcase opening with a diameter of 89mm, to make way for the cylinder skirt.
