OZ Cattiva Magnesium Rear Wheel BMW S1000RR K46 (2009-2018) C3063BM60X

Forged from premium magnesium by OZ's SBK Racing division, the Cattiva rear wheel represents the pinnacle of lightweight wheel engineering for the BMW S1000RR K46. As the lightest wheel in the entire OZ range, it delivers a measurable reduction in rotating mass that transforms agility, steering precision and corner-exit responsiveness on track.

Key Features

• Forged magnesium construction — the lightest wheel OZ produces, delivering exceptional strength-to-weight ratio for uncompromised track performance.
• Six-spoke Cattiva design developed by OZ's SBK Racing department, optimising stiffness distribution while shedding every gram possible.
• Reduced rotating mass sharpens turn-in response and improves high-speed stability through fast, sweeping corners.
• Made in Italy to OZ's exacting motorsport manufacturing standards, ensuring consistent quality and long service life under race conditions.
• Each wheel ships complete 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.

Build Quality and Materials

The Cattiva's foundation is aerospace-grade forged magnesium — a material chosen for its extraordinary combination of rigidity and low density. Unlike cast aluminium wheels, forged magnesium allows OZ's engineers to place material precisely where structural loads demand it, resulting in a wheel that is both lighter and stiffer. The six-spoke geometry, refined through OZ's involvement in Superbike World Championship racing, channels braking and acceleration forces efficiently from tyre to hub, keeping flex to a minimum and feedback to the rider at a maximum.

Track Performance

Every kilogram shed from a rotating component has a disproportionately large effect on how a motorcycle feels in transition. With the Cattiva fitted to the rear of your S1000RR, the reduction in gyroscopic inertia translates directly into faster direction changes, more responsive throttle-on exits and improved feel under hard braking. These are gains that compound over the course of a full track day, reducing rider fatigue as much as they improve lap times.

Fitment and Compatibility

This wheel is designed exclusively for the BMW S1000RR K46 produced between 2009 and 2018. It is compatible only with machines originally equipped with cast wheels. This wheel is intended exclusively for closed-circuit track use and is not approved for road use. The original BMW rear sprocket is not compatible — a suitable replacement sprocket carrier is included in the delivery scope.
