When homologation credentials are non-negotiable, the BST Rapid Tek Carbon Rear Wheel for the Aprilia RSV4, RSV4 RR, and RSV4 1100 Factory (2021–2026) delivers the reassurance you need. Carrying both DOT E and JWL certification, this wheel is fully road-legal and track-approved, so it goes wherever the RSV4's engine demands — without compromise. At just 3.20 kg (7.05 lbs), it also cuts rotating mass to a degree that transforms how the bike accelerates, steers, and responds.
Key Features
- DOT E and JWL certified — fully homologated for road and circuit use, giving you complete peace of mind on both the street and the race track.
- Ultralight construction at just 3.20 kg, reducing unsprung and rotating mass for sharper acceleration and noticeably more agile handling.
- Pre-preg carbon fibre rim joined to a CNC-machined 6082 T6 aluminium hub — a pairing that maximises stiffness-to-weight ratio while absorbing the stresses of hard riding.
- Engineered load ratings: radial load 451 kg (994 lbs), static load 280 kg (617 lbs), lateral load 772 Nm, torsional load 1,030 Nm — built for extreme sport riding conditions.
- Includes an ultra-high-speed 90° aluminium valve with cap, purpose-made for high-RPM operation.
- Backed by a 2-year manufacturer's warranty.
Build Quality and Performance
BST constructs the Rapid Tek rim using aerospace-grade pre-preg carbon fibre, a process in which resin-impregnated fibre layers are cured under precise heat and pressure to produce a structure that is simultaneously lighter and stiffer than a comparable aluminium casting. The hub is machined from 6082 T6 aluminium — a high-strength alloy chosen for its fatigue resistance under the sustained lateral and torsional forces generated by a 1,100 cc superbike. The result is a wheel that does not flex under load; every watt of power fed through the RSV4's drivetrain translates directly into forward motion.
Road and Track Use
The dual DOT E and JWL approvals are not merely a compliance box to tick — they represent independent, standardised load and impact testing that confirms this wheel performs safely under real-world conditions. Whether you are commuting between track days or pushing hard through a race weekend, the same certified wheel serves both roles. The ultra-high-speed 90° aluminium valve is designed to remain stable under the centrifugal forces generated at motorway and circuit speeds, maintaining consistent tyre pressure where a standard valve could falter.
The rear wheel is supplied as standard in the original fitment size. Alternative dimensions are available on request.
