Mazzucchelli Racing full cheek shaft 54 mm for Vespa PK125 XL2 / ETS
Shaft with 3 mm stroke for extra oomph on all smallframe engines. These are full cheek shafts for increasing pre-compression. The 3 mm extra stroke of the shaft can be divided between the foot and head gaskets depending on the desired engine characteristics. All in all, this is a very good way of influencing the cylinder characteristics as desired.
The connecting rod makes a solid impression. The lower bearing is very robust thanks to the silver cage. Particularly with directly aspirated cylinders with a corresponding speed range, care should be taken to ensure a sufficient mixing ratio of oil to petrol to lubricate the bearing. In order to install the shaft, the housing must be spindled accordingly. The cheeks have a larger diameter in order to be able to realize the additional stroke.
