OZ Gass RS-A Forged Aluminium Wheel Set for Kawasaki ZX-10 R (2021-2026)

Born on the WorldSBK circuit and engineered for the road, the OZ Gass RS-A forged aluminium wheel set delivers race-proven safety standards to every Kawasaki ZX-10 R rider. The dramatic reduction in rotating mass sharpens steering response, improves cornering stability, and raises the bar for every lap — whether that lap is a mountain pass or a circuit session.

Key Features

• Forged aluminium construction: exceptional strength-to-weight ratio reduces rotating mass for noticeably faster acceleration and more precise handling.
• Race and road certified: developed directly from WorldSBK competition hardware and validated for full road use — safety is never a compromise.
• Reduced unsprung weight: lighter wheels allow the suspension to respond more quickly, improving tyre contact and cornering confidence at all speeds.
• Four anodised colour options: gloss black, techno black, techno gold, and titanium — each finish applied for durability as well as aesthetics.
• Complete set: includes front and rear wheel, premium-grade bearings, aluminium angle-type valves, and spacers where required. A sprocket carrier is also included — note that the original rear sprocket is not compatible and must be replaced.
• Made in Italy: manufactured at OZ's Italian facility to the exacting quality and dimensional tolerances expected of a motorsport-grade wheel.

WorldSBK Heritage, Street-Legal Safety

OZ developed the Gass RS-A specifically to bridge the gap between professional Superbike racing and everyday road riding. The forged aluminium process — the same technology underpinning OZ's WorldSBK programmes — produces a wheel that is both stiffer and lighter than a cast equivalent, which translates directly into sharper turn-in, reduced braking distances, and a more connected feel through the handlebar. The anodised finish protects the alloy from corrosion and road contamination without adding unnecessary weight, ensuring long service life under demanding conditions.

Performance on Road and Track

For riders who use the ZX-10 R on track days as well as public roads, the Gass RS-A set removes the need to swap wheels between environments. The design balances outright stiffness — which is critical for consistent tyre loading during hard cornering — with enough compliance to remain safe and predictable on imperfect road surfaces. The result is a wheel that rewards an experienced rider without punishing everyday use.

Fitment and Compatibility

This wheel set is a direct replacement for the standard wheels on the Kawasaki ZX-10 R and ZX-10 RR, model years 2021 through 2026. The set includes all necessary bearings, aluminium angle valves, and spacers (where required). A sprocket carrier is supplied; the original Kawasaki rear sprocket is not compatible with this carrier and must be sourced separately. No additional machining or modification is required for fitment.
