Kyosho Motorcycle Steel Middle Gear by GPM SKM153  [SKM153]

Steel middle gear for Kyosho bikes

This steel middle gear is an aftermarket RC-scale replacement part supplied as 1pc and intended for Kyosho motorcycle models. It serves as the central stage in the model's drivetrain, transferring torque between the motor pinion and the spur set inside the gearbox.

Made from steel for improved wear resistance compared with common plastics, the part is best used where durability and consistent gear mesh are priorities during regular running or light tuning. It is not a full gearbox assembly but a single drivetrain component for RC motorcycles.

Installation notes: verify shaft alignment and bearing condition before fitting, confirm correct gear mesh with the existing pinion and spur, and avoid excessive preload on bearings. Use standard RC tools and check for smooth rotation across the full suspension travel to prevent binding.
