Crankshaft -MAZZUCCHELLI RACING (reed valve intake) full circle web, 54mm stroke- Vespa PK125 XL2, PK125 ETS (Ø=24mm cone)
Part no.:
1610013
Description
Shaft with 3 mm stroke for the extra bump in all smallframe motors.
These are solid cheek shafts to increase pre-compression. The additional 3 mm stroke of the shaft can be divided between foot and head seals, according to the desired motor characteristics. All in all a very good way to influence the cylinder characteristics as desired.
The connecting rod makes a solid impression. The lower bearing is very robust thanks to a silver cage. Especially with direct intake cylinders with an appropriate speed baffle, a sufficient oil/petrol mixture ratio should be ensured for lubricating the bearing.
In order to be able to install the shaft, the housing must be spun on accordingly. The cheeks have a larger diameter in order to be able to realize the additional stroke.
