Description
This primary pinion fits V50 and PK 50 XL 1 motors with original gear ratio. You only have to remove the clutch cover and replace the existing pinion on the crankshaft. The clutch basket can remain inside for assembly. This alternative is very interesting for all riders of 75ccm cylinders who want to increase the final speed of their scooter without much effort. By the Pinasco primary pinion an increase in speed of approx. 10 km/h is reached, which is also very helpful for the life span of the engine due to the speed reduction.
Possible transmission ratios:
- 14/69 (4th gear)93) Standard helical gearings
- 15/69 (4.60) Standard helical gearings
- 16/69 (4.31) Pinasco primary pinion
