Kyosho Motorcycle 25T CNC Aluminium Servo Arm and C8/C10 Steering Arm KM025TM26 by GPM  [KM025TM26]

Precision CNC aluminium servo and steering arms

The KM025TM26 two-piece aluminium kit replaces plastic servo horns and steering arms on Kyosho motorcycle models, delivering a stiffer interface between the 25T servo spline and steering linkage. Components are delivered in a matched C8 and C10 footprint for direct fitment to common Kyosho layouts.

Fitting procedure: remove OEM horn, align the CNC-machined arm on the 25T spline and secure using the serviceable retaining screw or OEM hardware. Standard hand tools suffice for installation and routine service.

Engineering rationale: aluminium decreases compliance under load versus injection-moulded plastics, producing improved feedback and repeatable centring during dynamic inputs. These parts are optimised for durability, precise spline engagement and predictable steering feel without modifying basic servo geometry.

Service notes: monitor spline engagement and fastener torque at scheduled intervals, inspect threads and contact surfaces after heavy use, and apply corrosion protection to exposed aluminium in corrosive environments.
