BST STAR TEK Carbon Rear Wheel – BMW M1000RR K66 (2021–2026)

Engineered for riders who refuse to compromise, the BST STAR TEK carbon rear wheel for the BMW M1000RR K66 (2021–2026) represents the highest standard in lightweight wheel construction. Its monocoque prepreg carbon shell, reinforced with BST's proprietary CRBNX carbon technology and a dedicated ultra-high-speed aluminium spider, delivers a dramatic reduction in rotating mass at the rear — translating directly into sharper acceleration, more responsive handling, and unwavering stability when powering out of corners.

Key Features

• Monocoque prepreg carbon construction using CRBNX technology for an exceptional strength-to-weight ratio
• BST ultra-high-speed aluminium spider integrated into the carbon shell for rigidity under extreme load
• Every wheel individually CT-scanned and inspected, with TÜV and JASO certification for road and track confidence
• Rated to a maximum load of 280 kg, with endurance testing spanning 1,000,000 bending and torsion cycles
• Available in a wide range of finishes: standard gloss, satin, matte, Forged Carbon, seven Candy colours, and six Solid colours
• ISO-certified manufacture backed by a 2-year warranty

Construction and Materials

The STAR TEK rear wheel is built around BST's monocoque carbon architecture — a single continuous carbon fibre shell rather than a bonded or bolted assembly. The prepreg layers are precision-laid under controlled conditions and cured under pressure, eliminating voids and ensuring consistent mechanical properties throughout. CRBNX technology further refines the layup to optimise stiffness exactly where the tyre and drivetrain forces are highest.

The aluminium spider is not a separate cosmetic element but a structural component machined to ultra-high-speed tolerances and fully integrated with the carbon rim. The result is a rear wheel that is both stiffer and considerably lighter than a comparable forged alloy item, with a quoted weight range of approximately 2.2–2.75 kg depending on specification.

Safety and Testing

BST's quality protocols go well beyond standard industry requirements. Each STAR TEK wheel undergoes 1,000,000 bending and torsion cycles in fatigue testing, 6,000 km of radial load simulation, and a radial impact test with residual air pressure retention validation — confirming that the wheel holds tyre pressure even after a significant kerb or pothole strike. After manufacture, every single wheel is CT-scanned internally and individually inspected before despatch. TÜV and JASO certification means the wheel is fully approved for road as well as track use.

Finish Options

The STAR TEK rear wheel is offered in an extensive range of surface treatments to complement any M1000RR livery. The standard gloss finish showcases the natural carbon weave. Satin and matte finishes offer a more understated look, while the Forged Carbon finish replicates the aesthetic of pressed carbon. For riders seeking colour, seven Candy options — including Candy Green, Candy Purple Blue, Candy Gold, Candy Orange, Candy Red, and Candy Blue — and six Solid colours — White, Red, Blue, Green, Silver, and a custom option — are available. Bearing choice covers both steel and ceramic options.

Fitment and Compatibility

This wheel is specifically designed and validated for the BMW M1000RR K66, covering model years 2021 through 2026. Size is 6.0 inches wide by 17 inches diameter, matching the OEM rear wheel specification for the M1000RR.
