The BST Mamba 7 TEK carbon rear wheel represents the pinnacle of lightweight wheel engineering for the BMW M1000RR K66. Constructed from aerospace-grade pre-preg carbon fibre and paired with a CNC-machined 6082 T6 aluminium hub, every detail speaks to uncompromising build quality — and at just 3.2 kg, the reduction in rotating mass delivers tangibly sharper acceleration, more responsive handling and improved suspension compliance, whether on road or circuit.
Key Features
- Pre-preg carbon fibre rim bonded to a precision CNC-machined 6082 T6 aluminium hub for exceptional rigidity with minimal mass
- Weighs only 7.05 lbs / 3.2 kg — a substantial reduction in unsprung and rotating weight over the stock wheel
- Available in three rear sizes: 6.0" x 17", 6.25" x 17" and 6.75" x 17" to suit different tyre and setup preferences
- DOT E and JWL certified for full road legality as well as unrestricted track use
- 90-degree high-speed aluminium valves with caps included as standard
- 2-year manufacturer's warranty for confidence in everyday and competitive use
Construction and Material Quality
BST's Mamba 7 TEK wheel is built around a pre-preg carbon fibre rim — the same manufacturing process used in MotoGP and high-end aerospace structures — where resin content is precisely controlled under heat and pressure for a consistent, void-free laminate. The hub is machined from 6082 T6 aluminium alloy, a grade chosen for its excellent strength-to-weight ratio and resistance to fatigue under repeated high-load cycling. The result is a wheel that not only weighs a fraction of a comparable cast aluminium unit, but is engineered to tolerate the structural demands of hard road riding and track use alike.
Performance on Road and Track
Reducing rotating mass at the wheel has a disproportionate effect on perceived performance: less inertia means the engine translates its output into acceleration more efficiently, while the suspension can respond to surface changes with less resistance. On the M1000RR K66 — a machine with the power to exploit every marginal gain — the Mamba 7 TEK rear wheel's load ratings of 451 kg radial, 280 kg static, 772 Nm lateral and 1,030 Nm torsional underline that none of this weight saving comes at the expense of structural integrity. The wheel is delivered as standard in the original equipment size; alternative sizes are available on request.
Fitment and Compatibility
This rear wheel is engineered specifically for the following model:
