Product Description

A wheel kit built with the same high-spec components as the AR1 racing wheel.
By combining Z-WHEEL’s R50 rim, Asterite hub, aluminum nipple set, and spoke set, this kit achieves exceptional strength while reducing weight compared to OEM wheels.

[ R50 Rim ]
A racing-spec rim developed for MX and Enduro competition. Constructed from premium A7050-T6 aluminum alloy and optimized in cross-sectional design, the R50 balances the competing demands of maximum strength and lightweight performance.

[ Asterite Hub ]
Precision-machined from a solid billet of high-strength aluminum alloy, the hub is reduced to one-tenth of its original mass while maintaining strength and a sleek appearance. Side cutouts not only enhance weight savings but also improve mud-shedding performance.

[ Aluminum Nipples & Spokes ]
Equipped with Z-WHEEL high-strength aluminum alloy nipples, reducing weight compared to stock steel nipples. The wheel set also features Z-WHEEL high-tensile stainless spokes—thicker in diameter for added durability. On the rear wheel, spoke count has been increased from 32 to 36, ensuring efficient power transfer to the ground.
