BST STAR TEK Carbon Rear Wheel – Aprilia RSV4 / RR / 1100 Factory (2021–2026)

Long days in the saddle or back-to-back track sessions demand a rear wheel that never becomes a liability. The BST STAR TEK Carbon rear wheel for the Aprilia RSV4, RR and 1100 Factory (model years 2021–2026) delivers an effortlessly composed ride thanks to dramatically reduced unsprung and rotational mass — so the suspension can do its job properly, the chassis stays balanced under braking, and rider fatigue across a full day's riding is genuinely reduced.

Key Features

• Monocoque prepreg carbon construction with proprietary CRBNX technology keeps the rim exceptionally light — approx. 2.2–2.75 kg depending on specification — for reduced rotational inertia and noticeably sharper acceleration out of every corner
• BST Ultra-High-Speed aluminium spoke hub provides the structural rigidity required for precise rear-end feedback whether you are threading a mountain road or pushing hard at the circuit
• Maximum rated load of 280 kg gives confidence for two-up touring and luggage use as well as solo track riding
• Every single wheel is CT-scanned and visually inspected before leaving the factory — quality is verified, not assumed
• Tested and approved to TÜV 287 StVZO and JASO T203-85 standards; endured 1,000,000 bend and torsion cycles, 6,000 km radial load running, and a radial impact test with residual air pressure retention
• ISO-certified manufacturing and a 2-year warranty underpin the premium price point
• A wide finish menu — Gloss, Satin, Matte, Forged Carbon, seven Candy colours and six Solid colours — lets you match or contrast the RSV4's livery exactly

Built for the Long Haul as Much as the Fast Lap

Carbon fibre wheels are often marketed purely for track use, but the BST STAR TEK's engineering philosophy is equally relevant to the demanding road rider. Lower rotating mass means the engine works less hard to maintain speed, reducing vibration transmitted through the drivetrain over extended distances. The CRBNX monocoque structure damps high-frequency road noise more effectively than a comparable aluminium rim, and the consistent geometry produced by ISO-certified layup processes eliminates the subtle imbalances that cause fatigue on longer routes.

The size — 6.0 inches wide by 17 inches diameter — matches the OEM specification precisely, so tyre choice remains completely unrestricted and fitting uses the standard hub interface.

Safety and Testing

BST subjects every STAR TEK wheel to a rigorous validation programme before it reaches a customer. Structural loading follows TÜV 287 StVZO and JASO T203-85 protocols. The bending and torsion rig runs to 1,000,000 cycles. Radial load endurance covers 6,000 km of simulated running. A radial impact test confirms that residual air pressure is retained after a strike. Finally, a CT scan and full visual inspection are completed on each individual wheel — not on a batch sample.

Finish Options

The STAR TEK is available in a choice of bearing specifications — steel or ceramic — and an extensive range of finishes. Standard Gloss lets the natural carbon weave speak for itself. Satin and Matte finishes give a more understated appearance. The Forged Carbon Finish replicates the aesthetic of forged composite material. Seven Candy colours (Green, Purple-Blue, Gold, Orange, Red, Blue) and six Solid colours (White, Red, Blue, Green, Silver, and more) allow full personalisation to suit any RSV4 colour scheme.
