Kyosho Motorcycle Delrin Middle Gear DKM153 upgrade by GPM  [DKM153]

Delrin middle gear details

This Delrin middle gear is an aftermarket replacement designed for Kyosho motorcycle models as a low-friction drivetrain component. It takes the place of the stock middle gear in the gearbox stack and helps deliver a smoother mesh with less audible noise compared to harder plastics.

Fitting is aimed at hobbyists comfortable with small gear trains: open the transmission area to access the middle gear, swap in the Delrin unit, check alignment against the pinion and spur gears, and confirm correct backlash while rotating the train before final assembly. Apply thread lock where required and avoid over-torquing fasteners that might distort plastic parts.

For setup and upkeep the Delrin middle gear helps reduce wear on mating metal gears and quiets the drive slightly. Regular checks of gear condition, correct bearing seating, and light lubrication at the mesh will extend service life and maintain reliable power transfer from motor to drivetrain.
