Kyosho Motor Cycle Aluminium Steering Post with Bearings by GPM KM048A  [KM048A]

Aluminium steering post with bearings

The GPM KM048A is an aftermarket RC-scale steering post designed for Kyosho motorcycle models, supplied as a 1pc set. Made from aluminium and supplied with ball bearings, this part replaces the standard plastic or stamped-metal post to improve rigidity where the steering assembly mounts to the front end of a model motorcycle chassis.

As a drop-in style hop-up, the steering post's role is primarily structural and positional: it locates the fork/steering assembly, maintains alignment under load, and serves as a wear point that can be replaced during maintenance. The included bearings reduce friction at the rotating junction compared with plain-bore replacements, helping to keep steering response consistent during running and after repeated use.

Installation is straightforward for anyone familiar with small-scale motorcycle disassembly: remove the front-end retaining fasteners, extract the original post, fit the bearings into the aluminium post if not pre-installed, then secure the new post with the original hardware. Check for correct axial play and retighten suspension linkages to manufacturer's torque to avoid binding. No special tools beyond common RC workshop hex drivers and pliers are required.

For tuning, the aluminium post provides a firmer mounting point that can slightly change steering feel by reducing flex; use it alongside incremental adjustments to fork geometry and shock setup rather than expecting a single-part transformation. Keep spare bearings on hand for routine servicing to maintain smooth rotation.

This aluminium steering post is a practical hop-up for Kyosho motorcycle scale models when you want a more robust steering pivot and lower friction at the rotation point, suitable for routine upgrades and periodic maintenance.
