DescriptionThe whole story▼
When the suspension of a lightweight sports bike like the KTM RC 390 reaches its limits, unwanted oscillations rob you of grip, stability and confidence. The Supreme Technology Oversuspension kit is a precision-engineered Italian solution built specifically for the RC 390 (2024–2025), drawing directly on Superbike and MotoGP development to give every rider — road commuter or track day regular — a measurably more composed and responsive chassis.
Key Features
- Precision-tuned resonator with a spring-weighted mass absorbs suspension oscillations at the point where the shock absorber reaches its operational limits, restoring traction and stability instantly.
- Manufactured in Italy to exacting quality standards, with each unit individually inspected — founder Nicola Bragagnolo's racing background is built into every component.
- Plug-and-play fitment requires no structural modification to the RC 390's chassis, keeping installation straightforward and reversible.
- Tangible gains in mid-corner stability and braking feel, particularly on broken or uneven road surfaces and during fast direction changes on track.
- Equally effective in urban traffic, fast road riding and dedicated track day use — a single upgrade that improves the bike across all conditions.
- Decades of real-world motorsport testing underpin the design, translating race-derived suspension technology directly to a production sports bike application.
Racing DNA, Road-Ready Engineering
The Oversuspension system works through a precisely calibrated resonator incorporating a spring weight. When the RC 390's shock absorber approaches its travel limits — under hard braking, over mid-corner bumps or during aggressive acceleration — this component counteracts the resulting oscillation cycle before it can unsettle the chassis. The effect is not subtle: riders consistently report more confident corner entry, better traction on the exit and a general sense that the bike tracks more faithfully over imperfect surfaces.
Supreme Technology was founded on a straightforward principle: the suspension intelligence developed over years of Superbike and MotoGP competition belongs on every rider's machine, not just factory race bikes. The result is a product range that feels premium because it genuinely is — not a rebadged aftermarket accessory but a purpose-developed chassis component with a clear engineering rationale behind it.
Made in Italy
Every Oversuspension unit leaves the Supreme Technology facility in Italy having been built and verified to the same standards applied to race-specification parts. The combination of motorsport experience and meticulous Italian craftsmanship produces a component that inspires confidence before you even fit it. Quality is visible in the finish, the tolerances and the precise feel of the assembly — details that distinguish a truly premium suspension upgrade from a generic alternative.
