Crankshaft -MAZZUCCHELLI RACING (rotary valve), Super Competizione, 51mm stroke, 97mm conrod- Vespa PK125 XL2, PK125 ETS (Ø=24mm cone)
Part no.:
1610010SC
Description
The Mazzucchelli Super Competizione crankshaft has a very long intake control angle.
Thus it generates even on an unmachined engine case intake already very much time cross section. By reworking the intake window in the engine case, more than 200° intake angles can be achieved without any problems. The shaft has the standard stroke and the standard connecting rod length.
It is therefore very well suited to build a powerful, rotary vane controlled motor with little effort. The Super Competizione has already been successfully used by us several times in racing operation.
