OZ Cattiva Magnesium Front Wheel Yamaha YZF-R6 RJ27 (2017-2026) C3177YA35X

When every fraction of a second on track counts, the OZ Cattiva Magnesium front wheel for the Yamaha YZF-R6 RJ27 (2017–2026) sets the benchmark for safety-validated, race-engineered construction. As the lightest wheel in the entire OZ range, it is forged from premium magnesium and engineered exclusively for track use — delivering a measurable reduction in rotating mass that transforms steering response, mid-corner agility and braking precision at the limit.

Key Features

• Forged from premium magnesium — the lightest wheel in the OZ catalogue, slashing rotating mass for faster direction changes and reduced gyroscopic load
• Six-spoke Cattiva design conceived by the OZ SBK Racing department, optimising the balance between structural rigidity and minimum weight
• Made in Italy to OZ's exacting manufacturing standards, ensuring race-grade reliability and longevity under sustained high-load track conditions
• Supplied complete with high-quality bearings, aluminium angled valves and spacers (where required) for a ready-to-fit installation
• Available in gloss black, matte black and gold finishes to suit individual livery preferences

Race-Engineered Construction

The Cattiva's forged magnesium construction is not simply a weight-saving exercise — it is a precision engineering statement. Forging aligns the grain structure of the metal, producing a wheel that is both lighter and stiffer than a comparable cast alloy unit. The result is a front end that communicates grip levels with exceptional clarity, allowing the rider to push harder and later with genuine confidence. The six-spoke architecture, developed directly from OZ's Superbike World Championship programme, channels load efficiently from tyre contact patch to hub, resisting flex under the extreme braking forces generated on circuit.

Performance on Track

Reducing rotating unsprung mass at the front axle has a compound performance benefit: the fork responds more quickly to surface changes, the tyre follows the road surface more faithfully, and the effort required to flick the R6 from one apex to the next is meaningfully reduced. Riders transitioning from the standard cast wheel to the Cattiva consistently report a sharper, more immediate front-end feel — the kind of feedback that builds confidence lap after lap. This wheel is built for riders who take track days and club racing seriously and demand components that keep pace with their ambition.
