OZ Piega R Forged Aluminium Rear Wheel – Aprilia RS 660 (2020-2026) R63065507

Developed directly by the OZ SBK Racing department, the Piega R rear wheel for the Aprilia RS 660 (2020-2026) strips away every gram that doesn't earn its place on track. Lighter than the standard Piega range, this five-spoke forged aluminium wheel reduces rotating mass where it matters most, delivering sharper turn-in, faster direction changes and more responsive handling at speed.

Key Features

• Forged aluminium construction — lighter than the standard Piega, with a stiffness-to-weight ratio tuned for circuit use.
• Reduced rotating mass improves agility and steering response at high speed.
• Five-spoke Piega R design conceived and validated by OZ SBK Racing engineers.
• Available in two anodised finishes: techno black and techno gold — both durable and visually distinctive.
• Made in Italy to OZ's exacting manufacturing standards for long-term reliability under race conditions.
• Includes quality bearings, aluminium angle valves, spacers (fitted as required) and a sprocket carrier — note that the original rear sprocket is not compatible and must be replaced.

Track-Focused Engineering

The Piega R designation signals a step beyond OZ's already accomplished Piega line. Where the standard Piega balances road comfort and performance, the R variant is optimised purely for the circuit. The forged aluminium construction allows tighter tolerances and a more favourable rotating-mass figure than a cast equivalent, and the geometry is matched precisely to the RS 660's swingarm and brake package for a clean, no-compromise installation.

The anodised finish is not merely cosmetic — it adds a layer of surface hardness that resists minor abrasion from tyre levers and pit-lane knocks, keeping the wheel looking sharp across a full season of track days. Techno gold adds a period-correct racing aesthetic; techno black is the understated choice for riders who want the performance without drawing attention to it.

Important Usage Note

The OZ Piega R is engineered exclusively for track use and is not approved for road or public highway use. The original Aprilia RS 660 rear sprocket is not compatible with the supplied sprocket carrier; a replacement sprocket will be required.
