Kyosho Motor Cycle 25T Aluminium Servo Arm by GPM KM025TM  [KM025TM]

25T aluminium servo arm for Kyosho motorcycles

This aluminium servo arm is an RC-scale replacement part produced by GPM for Kyosho motorcycle platforms, supplied as 1 pc. It uses a 25T spline interface (C8 style) to match standard 25-tooth servo splines commonly used on motorcycle-class models, and the aluminium construction offers a stiffer connection compared with many stock plastic arms.

Functionally it serves as the interface between the servo output shaft and steering or throttle linkages, allowing precise adjustments to throw and end points during tuning. The arm is useful when changing servo response characteristics, swapping between servos, or replacing a damaged horn to restore accurate steering feel on track or club runs.
