Oversuspension Vibration Damper Kit by Supreme Technology for Aprilia RS 660 (2020–2026)

Crafted in Italy from precision-machined aluminium and refined through years of elite motorsport collaboration, the Oversuspension kit by Supreme Technology redefines what a standard rear suspension setup can achieve on the Aprilia RS 660. Where most riders accept the limits of a factory shock absorber, this elegantly engineered rear-axle system works in harmony with the existing suspension to neutralise destructive resonance before it reaches the tyre contact patch.

Key Features

• Precision-machined aluminium cylinder housing integrates a resonator, spring and weight — a clean, purposeful assembly that mounts directly to the rear wheel axle
• Neutralises shock absorber resonance at the limits of travel, delivering measurably improved grip and braking performance even with ABS active
• Reduces tyre wear and rider fatigue on long road stages and track days alike
• Stabilises cornering lines in fast sweepers, giving the RS 660 a planted, confidence-inspiring feel
• Maintains optimal performance in wet conditions and across broken surfaces, significantly lowering aquaplaning risk
• True plug-and-play fitment — no modification to the frame or suspension linkage required

Design, Finish and Heritage

Supreme Technology was founded by Nicola Bragagnolo, who brings more than 25 years of hands-on motorsport experience to every product bearing the brand's name. The Oversuspension system is the distillation of that knowledge: a component conceived not in a marketing department but on the pit wall of international competition. The aluminium cylinder's machined finish speaks directly to that racing lineage — functional geometry with the kind of visual precision that looks at home on a machine as purposeful as the Aprilia RS 660.

The technology was developed and validated in close collaboration with professional riders including Michele Pirro, whose work with the Ducati Panigale V4 R programme informed the resonance-damping principles at the heart of the design. That pedigree transfers directly to road use: the same control and chassis precision that circuits demand is now available on every corner of every ride.

On the Road and on Track

The Aprilia RS 660 is a motorcycle that rewards precise, committed riding. The Oversuspension kit amplifies those qualities without altering the character of the chassis. When the rear shock approaches its travel limits under hard braking or mid-corner load, conventional setups introduce micro-vibrations that disturb tyre contact and reduce feedback. The Oversuspension resonator absorbs and redirects that energy, keeping the tyre loaded and the chassis settled. The practical result is shorter braking distances, more confidence in wet weather and a noticeable reduction in the tyre scrubbing that accumulates over an aggressive road ride or a track session.

Fitment and Compatibility

This kit is specifically engineered for the following model:

• Aprilia RS 660 — model years 2020 to 2026

Installation is carried out at the rear wheel axle. No permanent modification to the motorcycle is required, making removal and refitment straightforward for track day use.
