BST Rapid Tek Carbon Wheel Set – Aprilia RSV4 / RR / 1100 Factory (2021–2026)

DOT E and JWL certified for both road and track use, the BST Rapid Tek Carbon Wheel Set for the Aprilia RSV4, RSV4 RR, and RSV4 1100 Factory (2021–2026) represents the safest route to serious unsprung mass reduction — delivering sharper turn-in, faster acceleration, and more composed braking without any compromise on structural integrity. Pre-preg carbon fibre rims paired with CNC-machined 6082 T6 aluminium hubs make this the definitive upgrade for riders who demand homologated performance.

Key Features

• DOT E and JWL certified — fully homologated for road and race track use, no exemptions required
• Ultralight construction: front wheel weighs just 2.75 kg, rear wheel 3.20 kg for maximum unsprung mass reduction
• Pre-preg carbon fibre rims combined with CNC-machined 6082 T6 aluminium hubs for uncompromised rigidity
• Engineered load ratings well beyond road demands — front radial load 388 kg, rear radial load 451 kg
• Ultra-high-speed 90° aluminium racing valves with caps included as standard
• 2-year manufacturer warranty covering materials and workmanship

Safety, Certification and Structural Integrity

BST's Rapid Tek wheels are manufactured to pass both the American DOT E and the Japanese JWL standards — among the most demanding international approval protocols for motorcycle wheels. Every wheel is independently load-tested across radial, static, cornering and torsional axes before leaving the factory. The front wheel withstands a radial load of 855 lbs / 388 kg, a static load of 341 lbs / 155 kg, a cornering load of 577 Nm and a torsional load of 543.9 Nm. The rear wheel is rated to a radial load of 994 lbs / 451 kg, a static load of 617 lbs / 280 kg, a cornering load of 772 Nm and a torsional load of 1,030 Nm. These figures comfortably exceed the stresses generated during aggressive road riding and circuit use, giving you the confidence to push harder on every exit.

Construction and Materials

Each rim is formed from aerospace-grade pre-preg carbon fibre, a process in which resin-impregnated fibre plies are laid up under controlled conditions and cured under pressure, resulting in a void-free, fatigue-resistant structure with an exceptional strength-to-weight ratio. The hub is machined from 6082 T6 aluminium alloy — the same specification found in high-load aerospace structural components — and carries the bearing housings with tight tolerances to eliminate flex and maintain precise geometry under hard braking and cornering loads. A choice of steel or ceramic bearings allows you to match the specification to your riding environment.

Road and Track Performance

Reducing unsprung and rotating mass simultaneously produces compound benefits: the suspension reacts faster to surface changes, steering response sharpens, and the engine spends less energy spinning the wheels rather than propelling the motorcycle. On the Aprilia RSV4 platform, where the chassis geometry is already tuned for precision, the Rapid Tek set amplifies every quality the bike already possesses. Whether you are exploring the limits of a circuit or covering fast road miles, the reduction from a standard cast wheel to under 3 kg at each end is immediately perceptible in mid-corner stability and drive out of slow turns.
