Oversuspension Vibration Damper Kit by Supreme Technology for Yamaha YZF-R6 RJ27 (2017–2026)

When the shock absorber reaches its limit on a fast circuit, chassis composure separates fast lap times from lost seconds — and crashes. The Supreme Technology Oversuspension kit addresses that precise moment, engineering out the resonant vibrations that rob your Yamaha YZF-R6 RJ27 of rear-wheel traction, corner-exit drive and rider confidence. Conceived on international circuits and refined through seasons of Superbike and MotoGP collaboration, this is a genuine race-derived upgrade available for every R6 owner from 2017 to 2026.

Key Features

• Precision-machined aluminium cylinder integrating a resonator and spring weight to cancel shock-induced vibrations at the moment they occur
• Measurably reduces chattering and vibration under hard braking, acceleration and full lean — exactly the conditions that matter on track
• Improved rear-wheel traction and grip when powering out of corners, translating directly into quicker, more consistent lap times
• Noticeably more precise line-holding and cleaner chassis feedback so you can read the surface and adjust earlier
• Reduced tyre wear through smoother, more controlled damping — protecting your investment over a full track day or season
• Plug-and-play fitment requiring zero permanent modification to your R6

How the Oversuspension System Works

A conventional shock absorber generates resonant oscillations when it reaches stroke extremes — a phenomenon felt as chattering, instability and unpredictable grip loss. Supreme Technology's solution centres on a precisely machined aluminium cylinder housing an integrated resonator and spring weight. This assembly counteracts and absorbs those resonant frequencies before they propagate through the chassis. The result is more consistent damping across the full stroke, improved rear-wheel contact with the road or track surface, and a measurably more stable platform whether you are accelerating hard onto a straight, trail-braking deep into a hairpin or carrying maximum lean angle through a fast sweeper.

Race-Developed Expertise, Road and Track Ready

Supreme Technology developed the Oversuspension in direct cooperation with professional riders and validated it on international racing circuits. The company draws on decades of accumulated knowledge from the Superbike and MotoGP paddocks, engineering solutions that address real performance constraints rather than theoretical ones. Every kit is developed, manufactured and individually inspected in Italy under the direction of Nicola Bragagnolo — a guarantee of the precision and durability demanded at race level. The same performance that supports professional campaigns is now available as a straightforward bolt-on upgrade for your YZF-R6.
