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 is machined thinner than stock while maintaining full strength, achieving significant weight reduction. Side cutouts improve mud-shedding performance.

[ Aluminum Nipples & Stainless Spokes ]
Equipped with Z-WHEEL high-strength aluminum alloy nipples, reducing weight compared to stock steel nipples. The kit also features Z-WHEEL high-tensile stainless spokes.

[ Lightweight & High Rigidity ]
Uses a tubed lightweight rim compatible with enduro tires and bead stoppers. The hub is designed without a hub damper to prioritize weight reduction and direct handling. This wheel kit allows the versatile Serow to be customized for more cross-country oriented performance.

Precautions

Since the rear hub is designed to fit SEROW225W '93-99, the rear sprocket, sprocket nut, and sprocket nut washer must be replaced for SEROW225W '93-99.
