Supreme Technology Oversuspension Vibration Damper Kit for Aprilia RSV4 / 1100 Factory / R / RR / RF (2009–2020)

Engineered in Italy from precision-machined components and refined over 25 years of motorsport collaboration, the Supreme Technology Oversuspension kit brings genuine race-derived suspension technology to your Aprilia RSV4. Whether you are pushing hard on track or covering ground on imperfect road surfaces, this vibration damper system delivers measurably better traction, stability and rider confidence across the full RSV4 range from 2009 to 2020.

Key Features

• Precision-manufactured in Italy to exacting tolerances — every component reflects Supreme Technology's commitment to build quality over cost-cutting
• Internal resonator and spring cylinder actively cancels unwanted vibration at the rear axle, stabilising the swingarm under braking, acceleration and mid-corner loads
• Improved traction in corners and under hard acceleration, with a noticeably calmer feel over broken or uneven road surfaces
• Reduces tyre wear by smoothing out the micro-movements that scrub rubber prematurely
• Lowers rider fatigue on long rides by filtering vibration before it reaches the chassis and seat
• Plug-and-play fitment directly at the rear wheel axle — no machining, no modification, straightforward installation

Motorsport Heritage, Road-Ready Execution

Supreme Technology was founded by Nicola Bragagnolo, whose background in professional racing informs every product the company produces. The Oversuspension concept was developed in close partnership with race teams running superbikes at the highest level, including the Ducati Panigale V4 R, before being refined and validated for demanding road use. The result is an additional vibration damper that mounts at the rear axle and works in parallel with your existing shock absorber, extending its effective range when it approaches its limits under severe loading.

The internal mechanism — a precision cylinder housing a resonator and calibrated spring — absorbs and dissipates the high-frequency oscillations that conventional shock absorbers are not designed to handle. The effect is a suspension package that feels more cohesive and planted, particularly at high speed or when the road surface deteriorates. This is not a marketing claim; it is the outcome of over 25 years of competition-derived development distilled into a bolt-on upgrade.

Italian Craftsmanship You Can See and Feel

Each Oversuspension kit leaves Supreme Technology's Italian facility built to the same quality standard the brand applies to its race-spec components. The materials and manufacturing processes are selected to withstand the sustained mechanical stress of performance road and track use, not merely to pass a visual inspection. If you have invested in an Aprilia RSV4, this is the calibre of aftermarket component the chassis deserves.
