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

Overview of the Delrin middle gear

This Delrin middle gear serves as an aftermarket swap for Kyosho motorcycle models, offering a softer, lower-friction plastic option for the gearbox. It replaces the stock middle gear and is chosen where quieter mesh and gentler wear against metal mates are desired.

Installation suits experienced hobbyists: remove the gearbox cover to expose the middle gear, fit the Delrin replacement, align it with the pinion and spur gears and confirm correct backlash while turning the drivetrain by hand before tightening. Use appropriate thread locking where metal fasteners are required and take care not to deform the plastic with excessive torque.

During tuning and routine care, the Delrin gear helps limit wear on metal gears and smooths gear engagement. Periodic inspection of gear teeth, bearing fit, and a small amount of mesh lubricant will help maintain longevity and consistent power transfer from the motor to the drive system.
