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

Aluminium steering post with bearings

This KM048A aftermarket steering post is engineered for Kyosho motorcycle model front ends and supplied as a 1pc set. The aluminium post fitted with ball bearings replaces standard plastic or stamped-metal posts to improve structural rigidity at the steering assembly mounting point while reducing rotational friction at the pivot.

Functionally, the post locates the fork and steering assembly, preserves alignment under load, and acts as a replaceable wear interface. Bearings at the rotating junction lower friction compared with plain-bore installations, helping to maintain consistent steering response under repeated operating cycles.

Installation follows normal small-scale motorcycle procedures: remove front-end retaining fasteners, extract the original post, install bearings into the aluminium post if not preinstalled, and secure the unit with the original hardware. Verify axial clearance and torque suspension linkages to the manufacturer's settings to prevent binding. Standard RC workshop hex drivers and pliers are sufficient for fitting.

From a setup perspective, the aluminium post offers a firmer mounting point that can reduce chassis flex around the steering pivot; integrate this upgrade with minor fork geometry and damper adjustments for controlled handling changes. Keep spare bearings for scheduled servicing to retain consistent rotation and alignment.

A precision-focused hop-up, KM048A delivers a stronger pivot mounting and reduced bearing friction to support stable steering behaviour and easier maintenance on Kyosho motorcycle scale models.
