Small primary gear -DRT Gear Flame 3.72->3.53- Vespa V50, PV125, ET3. PK50, PK80, PK125 - 19 tooth

This sprocket fits V50 and PK 50 (XL I) engines with original gear ratio. 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.
