OZ Cattiva Magnesium Wheel Set Yamaha YZF-R6 RJ27 (2017–2026)

Developed by the OZ SBK Racing division, the Cattiva is the lightest wheel OZ produces — a forged magnesium construction engineered exclusively for track use. Fitted to the Yamaha YZF-R6 RJ27, this wheel set delivers a dramatic reduction in rotating mass that sharpens steering response, elevates cornering agility and raises the performance ceiling of one of the finest supersport machines ever built.

Key Features

• Forged magnesium construction — the lightest wheel in the entire OZ range, purpose-built for competitive track use
• Dramatic reduction in rotating mass for faster steering response, improved braking performance and more precise handling dynamics
• Complete set includes front and rear wheels, quality bearings, aluminium angled valves and spacers where required
• Rear sprocket carrier included — note that the original Yamaha rear sprocket is not compatible and must be replaced
• Direct replacement for the factory wheels on the Yamaha YZF-R6 RJ27 (2017–2026) — no modifications required
• Made in Italy by OZ's SBK Racing department to exacting motorsport standards

Racing Pedigree and Build Quality

The Cattiva name carries genuine motorsport credentials. Born out of OZ's Superbike racing programme, every wheel in this series is forged from premium magnesium alloy — a material chosen specifically because it combines exceptional strength with the lowest possible weight. The forging process aligns the grain structure of the metal, producing a wheel that is not only lighter than cast aluminium alternatives but structurally superior under the cyclic stresses of hard track riding. The result is a product that genuine racing professionals trust, now available in a direct-fit package for the RJ27-generation R6.

Track Performance

Reducing unsprung and rotating mass is one of the most effective ways to improve a motorcycle's dynamic response. Lighter wheels mean the suspension can react more quickly to surface changes, braking distances shorten, and the chassis pivots more freely through direction changes. On a circuit where tenths of a second matter, the Cattiva set gives the YZF-R6 RJ27 a measurable advantage — not just in outright lap time, but in the consistency and confidence a rider feels lap after lap. Available in gloss black, matte black and gold finishes, the set also makes an unmistakable visual statement in the paddock.

Fitment and Compatibility

This wheel set is designed as a direct, bolt-on replacement for the standard wheels on the Yamaha YZF-R6 RJ27. The following model year range is covered:
