DescriptionThe whole story▼
Born from OZ's SBK Racing division, the Cattiva magnesium rear wheel represents the pinnacle of Italian wheel-making craft — a forged magnesium centrepiece engineered exclusively for track use on the Yamaha YZF-R6 RJ27. Its signature six-spoke Cattiva design carries decades of motorsport heritage into every lap, pairing race-bred aesthetics with a dramatic reduction in rotating mass that transforms the way the R6 handles at the limit.
Key Features
- Forged from premium magnesium alloy — the lightest wheel in the OZ Cattiva range, delivering a meaningful reduction in unsprung and rotating mass for sharper turn-in and faster direction changes.
- Iconic six-spoke Cattiva architecture developed by the OZ SBK Racing department, maximising structural rigidity and torsional stiffness without adding unnecessary weight.
- Optimised exclusively for circuit use — engineered to maintain stability and composure at high speed through demanding corners where standard wheels begin to flex.
- Made in Italy to OZ's exacting manufacturing standards, ensuring consistent quality, long-term reliability and the finish integrity expected from a premium race wheel.
- Supplied with high-quality bearings, aluminium angle valves, spacers (fitted where required) and a dedicated sprocket carrier — note that the original rear sprocket is not compatible and must be replaced.
Design, Finish and Heritage
The Cattiva name has long been synonymous with OZ's most aggressive, track-focused wheel designs, and this rear wheel upholds that reputation entirely. The forged magnesium construction not only slashes weight compared with cast aluminium alternatives, it also lends the wheel a distinctly purposeful appearance — the kind of detail that is immediately visible to anyone who knows what they are looking at in the pit lane. Available in gloss black, matte black and gold, each finish is applied to complement the R6's own colour schemes and to signal unambiguously that this machine is built for the track rather than the road.
Heritage matters here. OZ has supplied wheels to factory-level Superbike and Grand Prix teams for decades, and the Cattiva line distils that experience into a wheel accessible to serious club and trackday riders. The six-spoke layout is not purely aesthetic — it is the result of extensive finite-element analysis aimed at placing material precisely where loads are highest, removing it everywhere else.
Performance on Track
Reducing rotating mass at the rear of a motorcycle has a disproportionate effect on agility. Less inertia in the wheel means the chassis responds more quickly to steering inputs, braking forces translate more directly into deceleration, and acceleration out of slow corners feels more immediate. On a circuit like the R6 was designed to dominate — technical, tight and demanding precise corner-speed management — these gains are not marginal. Riders switching from a standard cast wheel consistently report improved feel and confidence, particularly on the brakes and during direction changes.
Fitment and Compatibility
This rear wheel is developed specifically for the Yamaha YZF-R6 RJ27 from 2017 to 2026. It is designed for track use only and is not approved for road use. The standard OEM rear sprocket is not compatible; the included sprocket carrier requires a replacement sprocket. All necessary bearings, aluminium angle valves and spacers are supplied in the box.
