Wide Selection of Pinions for Tuning

Benefits of Choosing Aluminium Pinions

Each pinion is CNC finished to ensure consistent tooth form and reliable fitment with matching spurs. The reduced inertia from aluminium helps the motor respond faster when you change ratios, which is valuable when optimising lap times or trail response.

Where These Pinions Work Best

From fast circuit runs to technical off-road stages, the 21T-37T range covers most tuning needs. The supplied organiser tray keeps gears separated and easy to locate, so you can swap pinions trackside with minimal fuss.
