Stage6 HPC MKII crankshaft for Piaggio 50/70cc 2-stroke scooters.
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 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.
Conrod length: standard
Stroke: standard (39mm)
Gudgeon pin: standard (12mm)
Small end bearing: 12x17x15mm
Machined oil-pump drive, spacers, nuts & small end bearing included.
Stage6 S6-8014001
The big end bearing is not available as a spare part from Stage6. Usually the cost and time it takes to replace the big end bearing out weighs buying a new crank.
The pressure of the variator nut holds the cog in place when correctly spaced. The spline is not designed to take any drive load.
These are for pistons with a 12mm gudgeon pin (standard).
Yes it does
The crank comes with special silver small end bearing conrod bearings but crankshafts do not come with main bearings.
