Kyosho-Compatible 25T Aluminium Servo Horn and C8/C10 Steering Arm KM025TM26 by GPM  [KM025TM26]

Servo horn and steering arm replacement

The KM025TM26 kit provides two aluminium arms to replace standard plastic control arms on Kyosho motorcycle models, reinforcing the interface between a 25T servo spline and the steering linkage. Footprints provided match common C8 and C10 layouts used on Kyosho assemblies.

Fitting is quick on typical Kyosho motorcycles: remove the stock horn, fit the aluminium arm to the 25T spline, and secure with the original retaining screw or existing hardware. Only basic hand tools are required for routine replacement.

Why upgrade: aluminium reduces flex under load when compared to plastic, improving steering crispness and more predictable centring during hard throttle or braking. These parts are intended to refine control feel and durability without changing overall geometry.

Care and inspection: recheck screw torque after initial runs, monitor the spline and hardware for wear, and consider a light protective coating if models are exposed to damp conditions.
