OZ Gass RS-A Aluminium Wheel Set Aprilia RS 660 (2020-2026)

Engineered in Italy and forged from lightweight aluminium, the OZ Gass RS-A wheel set transforms the handling and acceleration of the Aprilia RS 660 across every environment — from the morning commute to a full track day. By significantly reducing rotating mass, these wheels sharpen the RS 660's responses in a way that no tyre or suspension upgrade can replicate.

Key Features

• Forged lightweight aluminium construction delivers an outstanding strength-to-weight ratio, reducing rotating mass for noticeably quicker acceleration and more agile direction changes.
• Designed equally for road and track use, offering a performance balance that suits everyday riding as well as circuit sessions without compromise.
• Complete set includes one front wheel and one rear wheel, supplied with quality bearings, aluminium angled valves, and spacers where required.
• A sprocket carrier is included in the set — note that the original Aprilia rear sprocket is not compatible and must be replaced.
• Available in four anodised finishes — gloss black, techno black, techno gold, and titanium — each providing a durable, corrosion-resistant surface that retains its appearance under hard use.
• Direct OEM replacement fitment for the Aprilia RS 660 (2020-2026), making installation straightforward without modification.
• Made in Italy: manufactured to OZ Racing's exacting quality standards, ensuring long-term durability and consistent dimensional accuracy.

Forged Aluminium — Why It Matters

The Gass RS-A name reflects OZ's commitment to forged wheel technology. The forging process aligns the grain structure of the aluminium, producing a wheel that is substantially stronger than a cast equivalent at a lower overall weight. For the Aprilia RS 660 — a machine that already rewards precise inputs — the reduction in unsprung and rotating mass sharpens steering feel and reduces the effort required to change direction at speed.

Road and Track Versatility

Unlike dedicated race-only wheels, the Gass RS-A set is homologated for road use, meaning you can run these wheels on your daily licence plates and switch to track tyres for a circuit day without swapping back to stock. The anodised finish on each colour option resists the brake dust, chain lubricant, and weather exposure that road use demands, while the structural integrity holds up to the lateral forces generated during hard cornering on track.

Fitment and Compatibility

This wheel set is designed as a direct replacement for the standard wheels on the Aprilia RS 660, covering model years 2020 through 2026. The sprocket carrier supplied in the kit is required because the original Aprilia rear sprocket is not compatible with the Gass RS-A hub. All other fitment hardware — bearings, angled aluminium valves, and spacers where applicable — is included.
