DescriptionThe whole story▼
Born on the WorldSBK grid and engineered to deliver that same competitive edge on track days and fast road riding, the OZ Gass RS-A forged aluminium rear wheel for the Kawasaki ZX-10 R (2021-2026) is a genuine performance upgrade. Reducing rotating mass at the rear axle sharpens throttle response, transforms mid-corner agility and cuts the inertia that holds a stock wheel back at the limit.
Key Features
- Forged aluminium construction delivers an outstanding strength-to-weight ratio — less rotating mass means faster acceleration, quicker direction changes and more responsive braking.
- WorldSBK-derived Gass RS-A design strikes the optimal balance between lightweight construction and structural rigidity under sustained track abuse.
- Available in four anodised finishes — gloss black, techno black, techno gold and titanium — each complementing the ZX-10 R's aggressive bodywork.
- Manufactured in Italy to the exacting quality standards OZ Racing is known for across MotoGP and Superbike competition.
- Dedicated fitment for the 2021-2026 Kawasaki ZX-10 R; supplied complete with quality bearings, aluminium angled valves, spacers (as required) and a sprocket carrier — note the OEM rear sprocket is not compatible.
Track Performance, Road Capable
The Gass RS-A is not a cosmetic upgrade dressed up as a performance part. The forged aluminium construction directly reduces unsprung and rotating mass — two of the most impactful variables in motorcycle dynamics. Less rotating inertia at the rear means the ZX-10 R responds more immediately to throttle inputs out of a corner, reacts quicker when you tip in and requires less effort from the suspension to follow surface changes at speed.
Whether you are chasing lap times at a club circuit, preparing for a trackday or simply want the sharpest-handling version of your ZX-10 R for mountain roads, the Gass RS-A delivers a perceptible difference that no suspension tweak alone can replicate. The anodised finish is not only durable against stone chips and brake dust — it gives the wheel a premium, race-ready appearance that stands apart from the factory item.
Italian Craftsmanship
Every Gass RS-A wheel is forged and finished in Italy. OZ's manufacturing heritage in motorsport means strict dimensional tolerances, consistent balance from the factory and long-term reliability through hard use. This is not a cast replica — it is a properly forged component built to withstand repeated track sessions and the thermal cycles that come with them.
Fitment and Compatibility
This rear wheel is designed exclusively for the Kawasaki ZX-10 R covering model years 2021 through 2026. The wheel is supplied with a sprocket carrier; however, the original OEM rear sprocket is not compatible and will need to be replaced when fitting this wheel. Spacers are included and fitted only where required. Please verify your exact model specification before ordering.
