This single-piece alloy rear wheel is a replacement hop-up intended for Kyosho motorcycle chassis where a stronger metal rim is required. The wheel employs a flat 4-hole (4H) mounting interface and is supplied as one unit for direct replacement when hub geometry matches.
Careful installation requires verification of hub alignment, axle fitment, and bearing compatibility with 走珠軸承 and hub spacers. During assembly, confirm thread engagement, apply correct fastener torque, and ensure bearings are seated squarely to avoid preload issues.
As a change to unsprung mass and rotational inertia, the alloy rim will affect transient traction and suspension response; assess damping, spring rates, and final drive ratios when integrating into a tuned chassis rather than expecting standalone performance gains.
Use this wheel only with compatible 4H hubs and follow precision RC fitting procedures to maintain predictable handling and longevity.
