Designed from the ground up for the Aprilia RS 660, this Spider Racing steering lock limiter carries the unmistakable hallmarks of the brand's racing pedigree: precise engineering, purposeful construction, and a finish that looks as deliberate as it performs. Part number 90.A235 brings a defined, repeatable steering stop to one of the most exciting middleweight sports bikes on the market, protecting critical chassis components at full lock — whether you are pushing hard on circuit or threading through the paddock.
Key Features
- Purpose-built for the Aprilia RS 660 (2020–2026) — no modification or fabrication required for a clean, factory-quality installation.
- Limits maximum steering travel to prevent contact damage to sensitive frame, fairing, and mechanical components at full lock.
- Constructed from track-proven, durable materials selected specifically for sustained racing and road demands.
- Plug-and-play fitment philosophy means installation is straightforward and reversible, with no permanent alterations to the motorcycle.
- Carries Spider Racing's motorsport heritage into a precise, repeatable steering geometry solution trusted on circuit.
Design, Finish and Heritage
Spider Racing has built its reputation supplying the paddock with components that bridge the gap between production sportsbikes and full race machinery. The steering lock limiter for the RS 660 reflects that ethos: clean lines, a purposeful profile, and surface quality that holds up under repeated track sessions. This is not a raw bracket crudely adapted to fit — it is a component conceived around the RS 660's specific steering geometry, so it sits flush, aligns correctly, and presents the kind of finish you would expect from a specialist accessory manufacturer with genuine racing credentials.
Performance and Protection
At extreme steering lock — during slow-speed manoeuvres, a fall, or an aggressive cornering moment — uncontrolled handlebar travel can force cables, brake lines, and fairing panels into damaging contact with the frame. The 90.A235 addresses this directly by establishing a firm, consistent limit on steering travel. The result is a defined handling envelope on track, reduced risk of expensive component damage, and the confidence that comes from knowing exactly where the bars will stop.
