Serpent SER120127 64P 40T Hard Aluminum Motor Pinion Gear - Precision Tune  [SER120127]

Tune Motor Output with the Serpent SER120127 Aluminium Pinion

The Serpent SER120127 motor pinion is a precision machined aluminium gear built to improve the responsiveness of your RC setup. With a 64P pitch and 40 teeth, this pinion gives accurate engagement and consistent performance for both track days and weekend runs.

Lightweight Yet Tough Construction

Made from hard aluminium, this pinion balances low mass with reliable strength to withstand repeated use while helping the motor spin with less inertial drag. That balance supports crisper acceleration without unnecessary weight.

Finer Pitch for Controlled Handling

The 64-pitch tooth form on this 40T pinion provides finer mesh accuracy for steadier throttle response and smoother transitions through corners. The refined pitch helps reduce gear lash and improves predictability under load.

Flexible Fit Across Models

Designed to suit many common RC drive setups, the Serpent SER120127 fits a broad range of motor applications and makes a practical upgrade when dialing in gear ratios or replacing worn pinions.
