Kyosho Motorcycle Replacement Middle Gear SKM153 by GPM  [SKM153]

Replacement middle gear for Kyosho bikes

This steel middle gear is supplied as a 1pc aftermarket replacement for Kyosho motorcycle models and serves as the central drivetrain stage, conveying torque from the motor pinion to the internal spur set.

Built in steel to offer improved wear resistance over typical plastic gears, the component is ideal where steady gear mesh and durability matter during normal running or modest tuning. It is a single gear element, not an entire gearbox.

Installation guidance: confirm bearing health and shaft alignment prior to fitting, match gear mesh carefully with the existing pinion and spur, and avoid over-tightening bearings. Rotate the drivetrain through full suspension movement to ensure there is no binding.
