This 2 piece set replaces the stock servo arm and steering arm found on Kyosho motorcycle RC models, offering a matched aluminium alternative to the original plastic parts. The kit is intended for 23T servo splines (C9) and the steering arm position C10 where those designations apply on Kyosho motorcycle assemblies.
Installation guidance: verify spline alignment prior to tightening, retain original mounting hardware where it fits correctly, and avoid over-tightening to prevent thread damage in the aluminium. Confirm that the servo spline and steering linkage clear at full travel to ensure unrestricted movement through suspension travel and steering range.
Tuning benefits: aluminium arms cut flex under load and provide more immediate steering feedback, helping when you are adjusting steering feel or centring. Check fastener threads and contact faces regularly and apply thread locker to steel screws if loosening occurs after driving.
