OZ Cattiva Magnesium Rear Wheel BMW S1000RR K67 with M Package (2019-2026) C6271BM60X

Forged from premium magnesium by OZ's SBK Racing division, the Cattiva rear wheel is the lightest wheel in the entire OZ collection — a genuine race-engineered component built for BMW S1000RR K67 riders who demand every possible advantage on track. The six-spoke Cattiva architecture strips rotating mass to a minimum, sharpening acceleration, braking response and cornering agility in a way that no cast aluminium wheel can match.

Key Features

• Forged magnesium construction — the lightest rear wheel in OZ's full lineup, delivering a measurable reduction in unsprung and rotating mass.
• Six-spoke Cattiva design developed by OZ's SBK Racing department, balancing extreme rigidity with the torsional precision demanded at race pace.
• Engineered exclusively for track use, unlocking sharper turn-in, faster direction changes and improved high-speed stability on the BMW S1000RR K67.
• Made in Italy to OZ's exacting production standards, ensuring long-term durability and repeatable performance across race weekends.
• Available in gloss black, matte black and gold finishes to suit individual livery preferences.
• Includes high-quality bearings, aluminium angled valves, spacers (fitted as required) and a sprocket carrier — note that the original rear sprocket is not compatible.

Build Quality and Materials

Where most aftermarket wheels begin with cast aluminium, the Cattiva starts with a forged magnesium billet — a material choice that defines the entire character of this wheel. Forging aligns the grain structure of the metal for superior strength-to-weight ratio, while magnesium's inherent lightness takes that advantage further than aluminium can reach. The result is a wheel that is not merely lighter on paper but demonstrably stiffer under cornering loads, resisting the micro-flex that can blur steering feedback at the limit. OZ's Italian manufacturing facility applies the same processes used to supply wheels to World Superbike and MotoGP teams, and every Cattiva reflects that heritage in its fit, finish and dimensional accuracy.

Performance on Track

Reducing rotating mass at the wheel alters the dynamic behaviour of the entire motorcycle. The S1000RR K67 already rewards precise rider inputs, and fitting the Cattiva rear wheel amplifies that responsiveness — corner entry becomes crisper, mid-corner attitude more adjustable, and drive out of slow corners noticeably more urgent as the engine no longer works against unnecessary rotational inertia. The six-spoke layout is not purely aesthetic: each spoke is profiled to carry load efficiently while contributing to overall torsional stiffness, ensuring the tyre contact patch stays consistent through compressions and direction changes alike.

Fitment and Compatibility

This wheel is designed specifically for the BMW S1000RR K67 equipped with the M Package, covering model years 2019 through 2026. It is not compatible with the standard S1000RR without the M Package axle specification. The original BMW rear sprocket cannot be reused — a new sprocket carrier is supplied in the box. Installation of the included spacers is required only where the build demands them. This wheel is intended exclusively for closed-circuit track use.
