Everyone knows this sort of problem. The original gear ratios are too short for cylinder kits which are increasing the power or capacity. Either the engine revs itself to death or the power is not transformed into a higher top speed. The bgm PRO primary gear is the first-aid kit to cure that. It can easily be fitted without separating the engine casings and even the clutch basket can remain in the engine casings. Perfect addition to kitted engines which still have the original 15 teeth primary drive sprocket (Four gear V50 up to the PK XL1). Gives an increase of approx. 10 km/h and the reduced revs go easy on the engine. Hardened to original manufacturer specification with 58 HRC.
