DESCRIPTION
The Naraku 16/37 +25% 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 secondary gears with a 16/37 ratio, offering a gear ratio approximately 25% shorter than the original ratio.

The secondary gear ratio—consisting of a 16-tooth pinion and a 37-tooth sprocket—determines the conversion of the rotary motion transmitted by the rear clutch/converter to the rear wheel. A shorter gear ratio means:

increased traction at low/mid-range RPMs

a noticeable improvement in acceleration

a more responsive mechanical feel

better use of engine torque

This kit is for riders who want a more dynamic ride, especially in urban environments, uphill, or with slightly modified engines.
