The Serpent 120130 Motor-pinion uses durable aluminium to keep tooth profiles accurate under load, helping your drivetrain run smoothly. The 64P/43T specification balances speed and torque for many RC setups.
The hard anodized coating reduces surface wear and helps the pinion tolerate the knocks and vibrations common in off-road running. That added protection supports longer service intervals.
Swapping pinion sizes around the 64P standard allows quick ratio adjustments to match tyres, track layout and motor torque. The 43T option is a practical step when chasing higher top speed.
