Kyosho Motor Cycle Delrin Main Gear by GPM DKM155  [DKM155]

Delrin main gear for Kyosho motorcycles

This RC-scale Delrin main gear is an aftermarket replacement part produced for Kyosho motorcycle models. Supplied as a single pcs item, the gear is intended for use in the motorcycle drivetrain where the main gear interfaces with the pinion and spur to transfer motor torque. The Delrin material offers low friction and good wear characteristics for plastic-to-plastic gear meshes commonly found in electric motorcycle kits.

Installation is straightforward for hobbyists familiar with small motorcycle gear trains: remove the gearbox cover, extract the worn main gear, and refit the replacement using the original hardware and bearings. When reinstalling, check axial play and set proper gear mesh to avoid excessive backlash or binding; a small visual gap is normal on Delrin meshes.

Tuning notes: Delrin teeth can run quieter than harder materials but may require periodic inspection for wear if you operate at high rpm or with aggressive gearing. Use light plastic-compatible grease sparingly at the gear face if required, and confirm the motor pinion alignment and bearing condition to preserve mesh consistency.
