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

Steering post, aluminium with bearing support

The KM048A steering post has been developed as an aftermarket replacement for Kyosho motorcycle model front ends and is supplied as a 1pc set. Constructed from aluminium and paired with ball bearings, it substitutes the original plastic or stamped post to enhance rigidity where the steering assembly mounts to the front of the chassis.

Designed as a straightforward hop-up, the post's primary functions are to position the fork and steering assembly accurately, keep alignment under load, and serve as a replaceable wear item. The bearings reduce rotational friction versus plain-bore alternatives, helping the steering feel stay consistent after frequent running.

Installation is simple for those comfortable with small motorcycle disassembly: remove the retaining screws at the front, extract the original post, press or place bearings into the aluminium post if required, then refit using the stock fasteners. Confirm correct axial clearance and re-tighten suspension connections to the manufacturer's torque values to prevent binding. Standard RC workshop hex drivers and pliers are sufficient for the job.

For those tuning handling, the aluminium post provides a firmer anchor that can alter steering response slightly by cutting flex; combine this upgrade with measured adjustments to fork geometry and damper settings. Keep spare bearings available for scheduled maintenance.

This aluminium steering post is a sensible upgrade for Kyosho motorcycle scale kits where a stiffer pivot and reduced friction are needed for consistent steering performance.
