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. The overlap on the crank pin is increased for maximum torsional rigidity. As a result, the crankshaft has a larger diameter (87 mm instead of 83 mm). This requires the crankcase to be spindled to Ø88 mm. This very sensible modification means that the shaft, together with the high-quality CNC connecting rod from Primatist, can also be used permanently in engines with over 30 hp.
Another special feature is the 6204 ball bearing used on both sides.
