The Taida 17/36 +31% Secondary Gear Kit is a high-performance secondary gear set designed for the final drive of scooters equipped with GY6 125cc to 150cc engines (e.g., Honda Ruckus GY6, Kymco, SYM, PGO). It replaces the original pinion/crown gear combination with a 17/36 ratio, resulting in a final drive ratio approximately 31% shorter than the original.
The secondary gear ratio—consisting of a 17-tooth pinion and a 36-tooth rear sprocket—determines the conversion of the CVT's output rotation to the rear wheel. A shorter final drive ratio:
increases the torque available at the rear wheel,
improves traction at low and mid-range RPMs,
provides more responsive acceleration,
optimizes engine response without requiring significant modifications to the engine.
This kit is for those who want:
more responsive driving in urban environments,
better acceleration uphill, when loaded, or in traffic,
more responsive traction without internal engine modifications.
