Motor pinions for Kyosho motorcycle tuning

An anodised aluminium set of motor pinions developed for Kyosho motorcycle models, supplied as a 3-piece set for rapid changes. The three pinions allow final drive adjustments without replacing the spur, preserving predictable rotational inertia while tailoring performance.

These pinions suit standard Kyosho motorcycle motor shafts sized for these pinion fittings. Swap the included 11T, 12T and 13T gears to alter acceleration or top speed during track testing, and monitor motor and ESC temperatures after each change. Intended for RC tuning and replacement use only.

Which pinions are included?

The set includes three anodised pinions: 11T, 12T and 13T, supplied together as a 3-piece kit for tuning or replacement.

How do I check compatibility?

Confirm your motor shaft diameter and spline configuration against the pinion specifications before fitting to ensure secure and correct installation.

Any setup recommendations?

Set correct gear mesh, torque the grub screw properly, and carry out short test runs while watching motor and ESC temperatures to verify the chosen ratio.
