Kyosho Motor Cycle Aluminium Steering Post by GPM KM048SP  [KM048SP]

Aluminium steering post for Kyosho motorcycles

This aftermarket steering post is an RC-scale replacement designed for Kyosho motorcycle models, supplied by GPM as KM048SP. It integrates an aluminium shaft with matched springs and ball bearings to support the steering linkage and convert servo input into controlled wheel movement. The description below focuses on fit, installation considerations, and how the part is used during setup and tuning.

Compatibility and role: the component is intended for Kyosho motorcycle steering assemblies where a compact steering post is required. As an upgrade or spare part, it serves both routine maintenance and tuning: the built-in springs provide preload for return action while the bearings reduce friction in the steering pivot.

Installation notes: inspect the existing steering linkage and mounting hardware before fitting, verify bore and shaft clearances, and replace one side at a time when possible to preserve alignment. Use appropriate thread-lock and torque on fasteners to prevent loosening during runs, and check servo horn alignment after installation to avoid binding.

Tuning and maintenance: adjust spring preload and check bearing freedom as part of steering setup; freer bearings reduce hysteresis while firmer preload can improve returnability. Periodic cleaning and light lubrication of bearings will maintain responsiveness, and re-check alignment after any trim changes to the servo or steering linkage.

This GPM KM048SP steering post is a direct aftermarket option for Kyosho motorcycle steering systems, intended for hobby-level replacement and tuning tasks where aluminium construction, springs, and bearings are preferred for predictable steering behavior.
