Precision Delrin pinions for motorcycle kits

This 2 piece Delrin pinion set in 13T and 14T is intended for use in Kyosho motorcycle kits where a low friction, quiet-running pinion is desirable. The parts are supplied to allow small incremental changes to pinion tooth count for tuning and replacement scenarios.

Delrin offers a favourable mix of dimensional stability and wear resistance under standard hobby motor loads, making the DKM135 pinions useful when performing gear ratio tests without altering the spur. The two tooth counts let technicians evaluate step changes in output speed and torque while maintaining mesh geometry.

Installation procedure: remove the motor per your model service instructions, mount the chosen Delrin pinion onto the motor shaft using the original retention method, set correct axial and mesh alignment, and verify free rotation before final assembly. Inspect shaft diameter and securing hardware for wear and confirm proper seating to prevent slippage under load.

What is delivered with the DKM135 kit?

The kit contains two Delrin motor pinions, one 13 tooth and one 14 tooth, supplied as a matched 2 piece set for evaluation and replacement use.

Performance notes for tuning applications?

Delrin performs well for low to moderate torque applications and offers quieter engagement than some plastics; for high torque or continuous high RPM applications monitor wear and consider metal pinions where necessary.

Recommended service checks after fitting?

After fitting, confirm correct mesh, check axial alignment and shaft seating, inspect fasteners, and perform a controlled low speed run to verify clearance and absence of binding.
