OZ Cattiva Magnesium Rear Wheel – Kawasaki ZX-10 R (2021-2026) C6125KA60X

Engineered exclusively for track use, the OZ Cattiva rear wheel for the Kawasaki ZX-10 R (2021-2026) is the lightest wheel in the entire OZ range — forged from premium magnesium and shaped by the OZ SBK Racing division to deliver a measurable reduction in rotating mass that transforms how your ZX-10 R changes direction, accelerates, and responds.

Key Features

• Forged premium magnesium construction — the lightest rear wheel OZ produces, delivering exceptional rotating mass reduction for race-level responsiveness.
• Exclusive 6-spoke Cattiva design developed by the OZ SBK Racing department, balancing structural rigidity with minimal weight for confident high-speed stability.
• Track-only specification engineered specifically for the Kawasaki ZX-10 R (2021-2026), ensuring precise fitment and optimised geometry for superbike-class performance.
• Made in Italy to OZ's exacting manufacturing standards, guaranteeing the reliability and durability demanded by competitive riders.
• Supplied with quality bearings, aluminium angled valves, spacers (fitted only where required), and a sprocket carrier — note that the original rear sprocket is not compatible and must be replaced.

Race-Proven Construction

Magnesium forging is the benchmark for serious track wheels. The material offers a superior strength-to-weight ratio compared with cast aluminium, and OZ's forging process refines the grain structure for added resilience under the extreme loads generated by modern superbike tyres on the limit. The Cattiva's 6-spoke layout is not a styling exercise — every spoke section and junction was shaped by the OZ SBK Racing department to distribute stress efficiently, keeping deflection to a minimum through fast corners and heavy braking events.

Track Performance Gains

Reducing rotating mass at the wheel has a disproportionate effect on how a motorcycle feels. Lighter wheels demand less energy to accelerate and decelerate, so throttle response sharpens, braking distances tighten, and mid-corner direction changes require noticeably less effort. On a circuit like the ZX-10 R demands — high entry speeds, late braking, quick transitions — the Cattiva translates directly into lap time. Riders consistently report improved agility and a more connected feel through the rear contact patch.

Fitment and Compatibility

This wheel is designed and homologated for track use only. It is a direct application for the following motorcycle:

• Kawasaki ZX-10 R — model years 2021, 2022, 2023, 2024, 2025, 2026

The original Kawasaki rear sprocket is not compatible with the supplied sprocket carrier. A suitable replacement sprocket must be fitted. Spacers are included but should only be installed where the application requires them. Always verify fitment details before installation and ensure the wheel is mounted by a qualified technician.
