Smaller front tooth counts (12T) generally give stronger acceleration with lower top speed, while combinations closer to stock balance both; exact effect depends on the rest of the CVT and tire setup. Precise speed/acceleration figures per combination are not verified.

Replaces the stock final reduction gear set inside the transmission case; requires opening the gearbox cover, recommended for an experienced mechanic. Package includes 1x gear set per selected combination.
