Instead of a single valve cutout for each intake and exhaust valve, the new '05 999R pistons feature a single cut for each pair. This allows unimpeded turbulence in the shallow combustion chamber for improved efficiency. Note also the cutaway section on the piston crown edge outside of each valve pocket, and the O-rings used to seal the coolant passages--the new engine does not use head gaskets.
