Kyosho Motorcycle KM153 Middle Gear Alloy Replacement by GPM  [KM153]

Replacement alloy middle gear for Kyosho motorcycles

The KM153 middle gear is supplied as 1 pcs and designed for Kyosho motorcycle drivetrains. As an aftermarket unit it sits between the motor pinion and the spur gear to transfer torque while resisting wear under regular use.

Installation notes: check axial alignment and gear mesh before tightening, use the original shaft and retaining parts, and ensure there is adequate clearance to adjacent bearings and the spur gear. Avoid forcing components into place and fine tune mesh by hand rotation.

Tuning and care advice: use an appropriate light grease on teeth, inspect bearing fit for endplay, and confirm ESC and motor settings remain unchanged after installation. Be cautious not to over-torque mounting screws to prevent undue stress on the alloy or gearbox housing.
