G- Final Drive Gear 52 (139QMB longcase)
Description: Final Drive Gear 52 Teeth direct stock replacement for 139QMB 49/50cc 4-stroke longcase engines. The final drive ratio is the last bit of gearing between your transmission and the driven wheels. In general, a lower final drive ratio will lead to less torque at the wheels but higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but lower top speed.
