Stage6 HPC Crankshaft CPI, HPC (High Primary Compression) crankshaft for 12mm piston pin.
HQ full-circle crankshaft for higher primary compression in the crankcase. It is entirely made of hardened steel, with reinforced connecting rod. Stage6 opted for a full-circle design instead of the standard design with inserts; this way the crankshaft has greater rotational inertia at high rpm. 16mm shaft (variator side), compatible with big variators (by Stage6, Polini, Malossi, etc.).
It is suitable for 50cc and 70cc sports, racing and even "Hyper Racing" engines.
Also included are an oil pump gear and a special variator nut.
- As it comes with a bigger nut, this crankshaft cannot be used with inner rotor ignitions by Polini or MVT.
- Variator-side shaft is 16mm.
