The control angle of this crankshaft corresponds to that of a standard 125cc shaft. This makes it equally suitable for the construction of a standard 125cc engine as well as a solid 133cc street tuning. The precise manufacturing, the material used and the good bearings enable many tens of thousands of kilometers of trouble-free mileage.
For higher performance requirements, we also offer the same shaft as a racing version with an extended intake control angle.
