OZ Piega R Aluminium Rear Wheel BMW M1000RR K66 (2021-2026)

The OZ Piega R is the track-focused evolution of OZ's acclaimed Piega range — an anodised forged-aluminium rear wheel engineered exclusively for BMW M1000RR K66 riders who demand the absolute maximum from their machinery. Shedding rotational mass precisely where it matters most, the Piega R delivers measurably sharper turn-in, faster acceleration response, and elevated high-speed agility that no standard wheel can match.

Key Features

• Track-only engineering: developed directly by the OZ SBK Racing department, the five-spoke Piega R design surpasses the standard Piega in both weight reduction and outright performance.
• Forged aluminium construction: premium-grade forged aluminium provides an exceptional strength-to-weight ratio, withstanding the sustained stresses of circuit use without compromise.
• Reduced rotational mass: lower unsprung and rotating weight transforms handling characteristics — steering becomes more precise, direction changes feel instantaneous, and corner-exit traction improves measurably.
• Anodised finish in two options: techno black anodised and techno gold anodised — both durable, corrosion-resistant finishes that retain their quality appearance under race conditions.
• Made in Italy: manufactured to OZ's exacting Italian production standards, ensuring dimensional accuracy, long-term reliability, and consistent performance session after session.
• Complete package: supplied with high-quality bearings, aluminium angle valves, spacing shims (where required), and a sprocket carrier — note that the original rear sprocket is not compatible.

Track Performance

Rotational inertia is one of the most consequential performance variables on a Superbike. By reducing the mass that the engine must accelerate and decelerate with every throttle input, the Piega R allows the M1000RR's inline-four to respond with greater immediacy. The five-spoke geometry, a signature of OZ's racing heritage, is optimised to balance torsional stiffness with the weight savings demanded at circuit level, making it the natural choice for club racers and professional teams alike.

Build Quality & Finish

Each Piega R wheel begins as a block of high-grade aluminium billet that is forged under pressure into a near-net shape, refining the grain structure for superior fatigue resistance. The anodising process penetrates the surface rather than coating it, meaning the finish resists chipping, peeling, and chemical attack from tyre sealants and cleaning products. Techno black delivers an assertive, circuit-ready aesthetic, while techno gold adds a distinct motorsport identity that references OZ's long history in professional racing.

Fitment and Compatibility

This rear wheel is designed and approved exclusively for the BMW M1000RR K66 covering model years 2021 to 2026. It is not compatible with any other BMW model or variant. The original BMW rear sprocket cannot be reused — the supplied sprocket carrier must be fitted with a compatible aftermarket rear sprocket.

Important Notice

The OZ Piega R is optimised exclusively for track use and is not intended for road registration or public road riding. Please confirm local motorsport regulations before use in competition.
