OZ GP Replica GP-8R Forged Aluminium Wheel Set for Yamaha YZF-R1/M RN32, RN49 & RN65 (2015–2026)

When lap times matter and every kilogram of rotating mass counts, the OZ GP Replica GP-8R wheel set delivers a genuine performance advantage for the Yamaha YZF-R1 and YZF-R1M. Forged from high-grade aluminium and shaped around a design proven on the world's most demanding circuits, this front-and-rear set transforms how the R1 turns in, tracks through corners and launches out of them — precisely the qualities that define a fast lap.

Key Features

• Forged aluminium construction reduces rotating unsprung mass, sharpening turn-in response and agility at the limit
• Authentic GP Replica GP-8R spoke architecture — the same motorsport lineage OZ supplies to top-level racing teams
• Direct fitment for Yamaha YZF-R1 and YZF-R1M chassis codes RN32, RN49 and RN65 (2015–2026) with dedicated Ergal 7075 bushings and spacers included
• OZ High-Density rear sprocket carrier supplied in the set — note: a new rear sprocket is required; OZ recommends the Sitta 201H
• Space-saving 90° aluminium valves and all mounting hardware included for a complete wheel upgrade out of the box
• Available in five anodised finishes — from circuit-focused Techno Black and Titanium to Gloss Gold — so the aesthetic matches your build

Track Performance, Road Precision

The Yamaha YZF-R1 and R1M are built around a crossplane-crank engine and an electronics suite borrowed from MotoGP — hardware that rewards a chassis set up for high-speed precision. Reducing rotating inertia at both axles through forged aluminium wheels amplifies exactly what OZ and Yamaha engineers already optimised: rapid direction changes, confidence under late braking and composed, predictable exits from tight corners.

On a trackday, the GP-8R set lets the R1's traction control and slide control systems work with a more responsive wheel package. On road, the reduction in gyroscopic effect from lighter wheels means the bike responds to rider input with noticeably less effort — a quality that compounds over the course of a long, fast ride.

GP-8R Design and Build Quality

The GP Replica name is not styling shorthand. OZ Racing supplies wheel technology to Grand Prix paddocks, and the GP-8R translates that lineage into a road and track-legal wheel set with the structural integrity a high-output superbike demands. The slender, multi-spoke profile is engineered to balance stiffness, strength and mass — each spoke carrying load efficiently without excess material. The anodised finish is applied for corrosion resistance as well as appearance, standing up to brake dust, road grime and trackday heat cycles.

Included Ergal 7075 bushings and spacers are machined specifically for the RN32, RN49 and RN65 chassis, ensuring correct bearing preload and axle alignment without modification. The OZ High-Density sprocket carrier is integrated into the rear wheel design; pairing it with the recommended Sitta 201H rear sprocket maintains the correct chain line and engagement geometry.

Available Finishes

The GP-8R wheel set for the Yamaha YZF-R1 and R1M is offered in five premium anodised finishes:

• Gloss Black anodised
• Techno Black anodised
• Techno Gold anodised
• Titanium anodised
• Gloss Gold anodised
