Kyosho Motorcycle Aluminium Steering Post with Bearings KM048A by GPM  [KM048A]

Aluminium steering pivot upgrade

The KM048A steering post is an aftermarket RC-scale part made for Kyosho motorcycle models, supplied as a single-piece set. Machined aluminium construction and ball bearings replace the stock plastic or stamped-metal post to increase stiffness where the steering assembly attaches to the front of the chassis.

As a drop-in hop-up, the post provides structural location for the fork and steering assembly, preserves alignment under load, and acts as a serviceable wear item. The fitted bearings cut friction at the rotating joint compared with plain-bore replacements, helping steering response stay consistent during runs and after repeated use.

Fitting is straightforward for anyone familiar with small-scale motorcycle teardown: remove the front-end retaining fasteners, withdraw the original post, press bearings into the aluminium post if they are not preinstalled, then secure the new post with the original hardware. Verify axial play and re-tighten suspension linkages to the manufacturer's recommended torque to avoid binding. No specialised tools beyond common RC hex drivers and pliers are required.

For setup, the aluminium post gives a firmer mounting point that can subtly alter steering feel by reducing flex; pair it with incremental fork geometry and damper changes rather than expecting a single-part transformation. Keep spare bearings to support routine servicing and smooth rotation.

A practical hop-up for Kyosho motorcycle scale models, this aluminium steering post provides a more robust pivot and reduced rotational friction, ideal for routine upgrades and maintenance.
