This matched 2 piece aluminium set replaces the factory servo arm and steering arm on Kyosho motorcycle RC platforms, replacing the original plastic parts while preserving intended geometry. The components are produced to match 23T servo splines (C9) and the steering arm C10 mounting position where those references apply on Kyosho motorcycle assemblies.
Assembly guidance: verify spline alignment and correct orientation before final torque, retain original mounting hardware where suitable, and avoid over-torquing to protect aluminium thread engagement. Confirm full-travel clearance of the servo spline and steering linkage to prevent interference across suspension motion.
Performance and service: upgrading to aluminium reduces torsional flex and improves steering feedback for finer adjustments to rate and centring. Inspect mating surfaces and fastener threads periodically and secure steel fasteners with a medium-strength thread locker if loosening is observed during operation.
