Front Sprocket 14T

This 14-tooth front sprocket is an alternative final drive ratio option for the Rush SR. The factory-default front sprocket is 15 teeth paired with a 44-tooth rear sprocket — swapping to a 14T front sprocket lowers the overall gear ratio, which shortens gearing for more acceleration at the cost of top speed. This makes it a useful choice for tighter, technical circuits where keeping the engine in its power band matters more than outright top-end velocity.

The front sprocket mounts to the engine output shaft and is compatible with the RK GXW 530 chain, which is the only chain recommended for the Rush SR. Removal and installation requires a 32mm socket. When changing sprocket sizes, inspect chain length and tension — a ratio change may require adding or removing links to maintain proper tension via the chain tensioner.
