Description High Compression Crankshaft for Piaggio / Aprilia 50cc 2T Scooters The full circle cranks do give a better filling of the cylinder thanks to the reduced space in the crankshaft casing. The SSC racing bearings do sustain the hardest revving engine setup. The twice slotted con rod with silver cage bearings at the big end and two holes for lubricating the small end bearing gives the best grade of reliability. The holes for balancing are filled with copper and alloy weights to get a ultra smooth running engine.
