OZ Gass RS-A Forged Aluminium Rear Wheel – Kawasaki ZX-10 R (2016-2020)

Born from OZ's involvement in the WorldSBK championship, the Gass RS-A rear wheel brings genuine race-derived engineering directly to your Kawasaki ZX-10 R. Forged from premium aluminium and precision-machined in Italy, it slashes rotational mass to sharpen steering response, lift agility and transform the way your ZX-10 R reacts at speed — on road or on track.

Key Features

• Forged aluminium construction delivers an exceptional strength-to-weight ratio, directly reducing unsprung and rotational mass for measurably improved handling.
• WorldSBK-inspired Gass RS-A spoke design optimises the balance between structural rigidity and lightweight build for both road and circuit use.
• Available in four premium anodised finishes — gloss black, techno black, techno gold and titanium — each applied to an exacting standard for lasting appearance.
• Made in Italy to OZ's highest manufacturing tolerances, ensuring consistent quality, durability and reliability over the long term.
• Precision-fit for the Kawasaki ZX-10 R (2016-2020): supplied with quality bearings, aluminium angled valves, spacers (where required) and a rear sprocket carrier — note that the original sprocket does not fit.

Engineering for Road and Track

The Gass RS-A is not a cosmetic upgrade — it is a measured performance intervention. By lowering the rotational inertia at the rear axle, the wheel allows the ZX-10 R's suspension to react more precisely to surface changes and lets the rider make direction changes with noticeably less effort. At high speeds this translates to a more planted, predictable feel; in the corners it means a more agile and communicative ride. The forged aluminium billet is shaped and machined in OZ's Italian facility under the same quality controls applied to their WorldSBK programme, making the Gass RS-A equally at home on a Sunday trackday as it is on a weekend road ride.

Anodised Finish Quality

Each finish — gloss black, techno black, techno gold and titanium — is an anodised treatment applied to the aluminium surface rather than a paint or lacquer. Anodising penetrates the metal itself, producing a finish that resists corrosion, abrasion and UV degradation far more effectively than conventional coatings. The result is a wheel that retains its appearance through repeated track sessions and varied weather conditions.

Fitment and Compatibility

This rear wheel is designed exclusively for the Kawasaki ZX-10 R covering model years 2016 to 2020. The package includes all hardware required for fitment: quality bearings, aluminium angled tyre valves, and spacers where needed. A dedicated rear sprocket carrier is supplied; the standard OEM Kawasaki rear sprocket is not compatible and must be replaced accordingly.
