The Stage6 HPC MKII (high primary compression) crankshaft is a full-circle crankshaft, and as such increases primary compression in the crankcase. It has been developed in cooperation in Germany and is completely made of metal (i.e. no plastic padding). The bearings can handle up to 16,000 rpm!
Particular attention has been paid to the Piaggio crankshaft. With completely reinforced shaft the way you know it from MHR Team crankshafts. Comes with machined oil-pump drive and spacer
Made in Italy.
Stage6 S6-8014001
