Developed alongside professional test riders on European superbike circuits, the Supreme Technology Oversuspension kit brings race-validated rear suspension control to the Yamaha YZF-R6 RJ11 and RJ15. Every component is precision-manufactured in Italy under the direction of Nicola Bragagnolo, so the engineering integrity behind this upgrade is as serious as the results it delivers on road or track.
Key Features
- Race-derived resonator with spring weight actively compensates for rear suspension oscillations, delivering faster and more consistent shock absorber response
- Measurably reduced chattering and vibration at high speeds, giving the rider a calmer, more planted feel through fast corners
- Improved turn-in precision and line-holding — the suspension tracks intended arcs rather than reacting to unwanted harmonic movement
- More even tyre loading across all conditions, extending rear tyre life and maintaining consistent grip levels throughout a session
- Plug-and-play installation — fits directly to the existing rear suspension without modification or special tooling
- Enhanced suspension feedback translates into greater rider confidence whether commuting, touring sport roads or lapping a circuit
The Technology Behind the Kit
The Oversuspension system centres on a finely tuned resonator paired with a calibrated spring weight. Together they absorb and neutralise the harmonic vibrations that build in the rear suspension assembly under load, particularly during hard acceleration and aggressive braking. By eliminating these oscillations at the source, the shock absorber can do its job without fighting interference — the result is a rear end that feels composed where a standard setup would begin to feel vague or nervous.
Racing Expertise, Road-Legal Performance
Supreme Technology bases its product development on genuine motorsport data. The Oversuspension kit was tested and refined in collaboration with professional riders on superbike-class circuits across Europe before being signed off for production. That process ensures the calibration suits real-world riding conditions — not just controlled test environments — so road riders benefit from the same level of precision and control that informed the original race specification.
Made in Italy
Every Oversuspension system leaves the Supreme Technology facility in Italy having been assembled with close dimensional tolerances and high-grade materials. The brand's commitment to manufacturing quality is reflected in the consistency of the product and the confidence riders report after fitting. This is not an aftermarket approximation — it is a purpose-engineered suspension component built for the demands of the R6 platform.
