Crankshaft -MAZZUCCHELLI Racing (rotary valve)- Vespa PV125, ET3 125, PK80 S, PK125 S (Ø=19mm cone)
Part no.:
1610008
Description
In order to achieve higher speeds, one should reach for the racing shaft. The extended intake timing results in a much freer engine revs. This measure is especially noticeable with high-revving cylinders.
The quality of the crankshafts is very good and so they resist even the highest revs. Especially for the higher capacity engines from 125cc they are an optimal supplement to extend the usable speed range of racing cylinders without spitback in the lower speed range.
These engines offer both, a decent torque over the whole speed range and a free coasting without the engine running out of air on inclines.
