Kyosho Motor Cycle Delrin Motor Gear (13T, 14T) by GPM DKM135  [DKM135]

Delrin motor gear for Kyosho motorcycles

This is a 2pcs set of Delrin motor gears supplied by GPM for Kyosho motorcycle models, offered in 13T and 14T sizes. The gears are intended as RC-scale replacement parts for small displacement electric motorcycle kits where Delrin is preferred for reduced friction and quieter mesh under light loads.

Use these gears when you need to change pinion tooth count for gearing experiments or to replace worn plastic pinions. Delrin offers a balance between dimensional stability and wear resistance for typical RC motor outputs, and the two sizes let you test small steps in gear ratio without changing the spur gear.

Installation notes: remove the motor from the chassis using the manufacturer’s procedure, slide the selected Delrin gear onto the motor shaft matching the original retaining method, check gear mesh and axial alignment, and verify free rotation before reassembly. Inspect the motor shaft and securing hardware for wear and correct fit, and run a low-speed test after installation to confirm mesh and clearances.
