cylinder and piston

The extremely short 88mm bore cylinder, features a reworked cooling concept that works together with the new, forged bridged box-type piston made by CP. The piston crown geometry has been adapted to suit the high-compression combustion chamber. Despite its incredibly low weight, it has an extra rigid structure for enhanced durability. Thanks to its lightweight construction, the oscillating masses are low, giving the engine extremely lively characteristics. To further improve engine performance, the compression ratio has been increased from 12.3 to 13.5 : 1.
