High quality tuning shaft from Fabbri Racing. Suitable for all smallframe engines with cylinders from 125cc and diaphragm inlet on the cylinder or in the crankcase. For maximum torsional safety, the overlap at the crankpin is increased. Thus the crankshaft has a larger diameter (87mm instead of 83mm). This requires a spindling of the crankcase to Ø88mm. By this very reasonable modification the shaft can be used together with the high-quality CNC connecting rod of Primatist also durably in engines with over 30 HP.
Another special feature is the 6204 ball bearing used on both sides.
