Kyosho-compatible 25T servo arm aluminium KM025TM by GPM  [KM025TM]

25-tooth aluminium servo arm for Kyosho bikes

This aluminium servo arm is an RC-scale replacement part supplied as 1 pc for Kyosho motorcycle platforms. It attaches to a 25T spline (C8 style) commonly used on motorcycle servos, and the aluminium design reduces flex compared with many original plastic horns.

The arm functions as the mechanical link between the servo output shaft and steering or throttle linkages, enabling accurate throw adjustments and endpoint trimming during setup. It is useful when upgrading servos, swapping components, or replacing a damaged horn to recover consistent steering feel.
