BST STAR TEK Carbon Rear Wheel – Aprilia RSV4 / RR / RF / 1100 Factory (2015–2020)

Every BST STAR TEK carbon rear wheel ships individually CT-scanned and TÜV-certified, making it one of the most rigorously validated lightweight wheels available for the Aprilia RSV4, RR, RF and 1100 Factory (2015–2020). The monocoque Prepreg carbon construction — built with BST's proprietary CRBNX technology — slashes rotating mass at the rear axle, rewarding you with explosive drive out of corners and a level of feedback that cast aluminium simply cannot deliver.

Key Features

• TÜV 287 StVZO and JASO T203-85 certified — every individual wheel passes bending and torsion tests to 1,000,000 cycles, 6,000 km radial load testing and a radial impact test with residual air pressure retention before it leaves the factory
• CT-scanned individually — internal structure verified by computed tomography on each unit, not just batch samples, ensuring zero hidden voids or delamination
• CRBNX Prepreg carbon monocoque — the entire rim structure is formed as a single continuous shell, eliminating bonded joints and maximising stiffness-to-weight ratio
• BST Ultra-High-Speed aluminium spider — combines the carbon hoop with a precision-machined aluminium centre rated to a 280 kg permissible load
• Approx. 2.2–2.75 kg depending on finish — a genuine reduction in unsprung and rotating mass that sharpens acceleration, braking and mid-corner stability
• ISO-certified manufacture, individual serial number and a 2-year warranty included as standard
• 14 finish options — from standard Gloss carbon to Satin, Forged Carbon, and a full palette of Solid and Candy colours

Safety Testing — the Full Picture

BST subjects the STAR TEK to a test programme that exceeds what most road-legal carbon wheels are required to meet. Load tests follow TÜV 287 StVZO and JASO T203-85 protocols. Bending and torsion cycling runs to 1,000,000 complete cycles. Radial load endurance covers 6,000 km. A radial impact test confirms the wheel retains air pressure after a sharp kerb strike. Finally, every finished wheel is CT-scanned before despatch — not a sample from the batch, but the exact wheel you receive. That individual inspection record, combined with the serial number and ISO-certified production process, is the reason BST backs each wheel with a 2-year warranty.

Construction & Performance

The STAR TEK's monocoque architecture means the carbon rim is laid up as one continuous structure rather than being bonded from separate sections. BST's CRBNX technology controls fibre orientation and resin content to a degree that injection-moulded or wet-lay processes cannot match, delivering a rim that is simultaneously stiffer and lighter than the OEM forged aluminium wheel it replaces. The BST Ultra-High-Speed aluminium spider bridges the carbon hoop to the wheel bearing, handling the lateral and torsional loads generated under hard acceleration and braking without compromising the weight advantage of the carbon structure.

On the road or the track, the drop in rotating inertia is immediately apparent. The rear end responds faster to throttle inputs, the bike changes direction with less effort and the reduced gyroscopic effect gives the chassis greater freedom mid-corner. For RSV4 owners who have already optimised suspension and tyres, upgrading to the STAR TEK rear wheel is one of the highest-impact single modifications remaining.
