Kyosho Motorcycle Middle Gear SKM153 Replacement by GPM  [SKM153]

Middle gear in steel for Kyosho motorcycles

This steel middle gear is an aftermarket RC replacement supplied as 1pc and intended for Kyosho motorcycle platforms. It serves as the central gear in the gearbox, passing torque from the motor pinion to the spur set.

Chosen for its steel construction, the component provides better wear resistance than many plastics and is suited to situations where consistent gear mesh and durability are needed during normal running or modest tuning. It should be treated as a single drivetrain part, not a full gearbox replacement.

Fitting advice: inspect bearings and shaft alignment before installing, verify gear mesh with the pinion and spur, and avoid excessive bearing preload. Use standard hobby tools and move the suspension through its range to check for smooth operation and no binding.
