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 offers superior strength compared to OEM components.


[ 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 ]

Cylindrical high-strength aluminum alloy is precision-machined to 1/10th of its original weight, providing a visually striking design while emphasizing strength and weight reduction. Side cutouts improve mud-shedding performance.


[ Aluminum Nipples & Spokes ]

Equipped with Z-WHEEL high-strength aluminum alloy nipples for reduced weight compared to stock steel nipples. The kit also includes Z-WHEEL high-tensile stainless spokes.


[ Hub Design Feedback from Motocross ]

The hub design is based on motocross hubs, adapted for the DRZ400S/SM. Fully machined from high-strength aluminum alloy, it provides greater rigidity and reduced weight compared to stock cast hubs. Models from 2004 onward feature a hub without a damper, offering lighter weight and a more direct feel.

Precautions

  • All parts are designed exclusively for the complete kit and are not factory-compatible.
  • When installed on DRZ400SM, the speedometer cannot measure the speed correctly; it is necessary to replace it with the stock meter gear for DRZ400S.
  • Not compatible with hub damper. When installing on a stock vehicle with hub damper, it is necessary to replace the rear sprocket and sprocket side spacer for 2003 or earlier DRZ400S models.
