Race-Grade 21T Pinion from Tamiya

The Tamiya 53731 Racing Clutch Pinion Gear, featuring 21 teeth, is aimed at precise first gear tuning. It allows measured changes to gearing to better match motor characteristics and circuit profile.

Balance Speed and Torque

Swapping to the Tamiya 53731 lets you shift the balance between acceleration and top speed to suit lap demands. Small pinion steps are useful for fine tuning on technical tracks.

Cross-Model Compatibility

Compatible with many Tamiya models, this pinion is a versatile choice for racers with multiple cars. It can be combined with Tamiya pinions such as 53733, 53734 and 53735 to explore different gear setups.

Consider track length and surface: shorter technical tracks favour quicker acceleration and a smaller pinion, while faster layouts may benefit from a larger pinion for higher top speed.
Changing pinion size changes load on the clutch; check clutch settings and inspect shoes and bell regularly to avoid premature wear when trying new ratios.
Yes, carrying a small selection of pinions including the 53731 lets you test and adapt ratios between qualifying and finals to suit evolving track conditions.
Most hobbyists can fit a pinion with basic tools, though precise mesh setting and clutch checks are important. Seek assistance if you are unsure about gearbox alignment.
Bring a small set of pinions, spare grub screws, a mesh gauge or feeler, and basic tools to swap and set mesh quickly between sessions.
