DescriptionThe whole story▼
Born on the WorldSBK pitlane and engineered for every rider who demands the same competitive edge, the OZ Gass RS-A rear wheel delivers a measurable reduction in rotating mass that sharpens acceleration, braking response and high-speed agility on both circuit and road. Forged from premium aluminium and finished to OZ's exacting Italian standards, this is the upgrade that changes how your Yamaha YZF-R1 or R1M actually feels to ride.
Key Features
- Forged aluminium construction slashes rotating mass for faster acceleration and more precise corner entry on track and road alike.
- Direct WorldSBK heritage — the Gass RS-A design was refined through top-level racing competition before reaching the street.
- Available in four premium anodised finishes: gloss black, techno black, techno gold and titanium — each complementing the R1/M's aggressive styling.
- Precision-engineered for an exact OEM fit on the Yamaha YZF-R1/M RN32, RN49 and RN65 chassis — no guesswork, no adaptation required.
- Supplied with quality bearings, aluminium valve stems and spacers (fitted only where needed), plus a sprocket carrier — the original rear sprocket is not compatible.
- Made in Italy — OZ's manufacturing heritage guarantees dimensional accuracy, structural integrity and long-term durability.
Track Performance, Road Refinement
The core principle behind the Gass RS-A is simple: less rotating mass means the engine's power reaches the tarmac more efficiently. On circuit, the gains are immediately apparent — the R1 changes direction with noticeably less effort, braking distances tighten up and the front end communicates more clearly because the rear is no longer fighting inertia. On the road, the same physics translate into a more lively, responsive ride that makes every corner feel more rewarding.
OZ has engineered the Gass RS-A to balance lightweight construction with the structural rigidity a high-performance superbike demands. The forged process aligns the grain structure of the aluminium, producing a wheel that is simultaneously lighter and stronger than a comparable cast unit — a characteristic particularly valued under the sustained stress of track use.
Finish & Aesthetics
Each Gass RS-A wheel is anodised rather than simply painted, meaning the finish is integral to the aluminium surface rather than a coating sitting on top. The result is a depth and consistency of colour that resists chips and corrosion far better than conventional finishes. The four available colourways — gloss black anodised, techno black anodised, techno gold anodised and titanium anodised — pair naturally with the Yamaha YZF-R1/M's factory livery options as well as popular aftermarket schemes.
Fitment & Compatibility
This rear wheel is designed and tested specifically for the following models:
- Yamaha YZF-R1 RN32 (2015-2016)
- Yamaha YZF-R1M RN32 (2015-2016)
- Yamaha YZF-R1 RN49 (2017-2020)
- Yamaha YZF-R1M RN49 (2017-2020)
- Yamaha YZF-R1 RN65 (2021-2026)
