Kyosho Motorcycle Delrin Pinion Set 13T & 14T DKM135 by GPM  [DKM135]

Delrin motor pinions for Kyosho motorcycle kits

This 2 piece Delrin pinion set offers 13T and 14T sizes intended as replacement or tuning pinions for Kyosho motorcycle models. Delrin is used where reduced friction and quieter operation under light loads are priorities.

The DKM135 pinions let you change the motor tooth count to test small gear ratio steps or to replace worn plastic pinions. Delrin provides stable dimensions with decent wear resistance appropriate for common RC motor speeds, so you can adjust gearing without changing the spur.

Fitting guidance: remove the motor according to your vehicle procedure, mount the selected Delrin pinion on the shaft using the original retention, set correct mesh and axial runout, then confirm free movement before reassembly. Check shaft condition and securing hardware, and run a slow test after installation to ensure correct clearances.
