Adjustable motor pinion set for Kyosho bikes

Lightweight anodized aluminium pinions made for Kyosho motorcycle models, supplied as a 3pcs kit to speed up gear changes. The three pinions (11T, 12T, 13T) let you change the final drive ratio without swapping the spur gear, helping you tune torque response and top speed with minimal weight penalty.

These pinions are intended for standard Kyosho motorcycle motor shafts that accept these sizes. Swap between the included gears to soften or sharpen throttle feel during setup runs, and monitor motor and ESC temperatures while testing. This set is for RC tuning and replacement use only.

What comes in the 3pcs kit?

The package contains three anodized aluminium pinions: one 11T, one 12T and one 13T, supplied together for quick on-track swaps or spare parts.

Will these fit my Kyosho motor shaft?

They are designed for Kyosho motorcycle applications; verify your motor shaft diameter and spline type before installation to ensure correct fitment.

Any tips for installation?

Clean the shaft, fit the correct grub screw and torque, and set proper mesh with the spur gear. Run a short test and monitor temperatures after changing tooth counts.
