Product Description

A wheel kit built with the same high-spec components as the AR1 racing wheel. By combining Z-WHEEL’s R50 rim, Asterlite 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.

[ Asterlite Hub ]
Crafted from high-strength material, the hub can be machined thinner than stock while maintaining full strength, achieving significant weight reduction. Side cutouts improve mud-shedding performance.

[ Aluminum Nipples & Spokes ]
Equipped with Z-WHEEL high-strength aluminum alloy nipples, reducing weight compared to stock steel nipples. The kit also includes Z-WHEEL dedicated spoke set.

[ Asterlite Hub Conversion Feature ]
For the WR250X front, the brake disc mounting position matches the stock setup, making conversion easy, while the hub alone reduces weight by approximately 550g. Bearings and seals are designed to be compatible with OEM sizes.
