When every tenth of a second counts on circuit, the BST Mamba 7 TEK carbon rear wheel gives Yamaha YZF-R1 and R1M riders a genuine performance edge. Tipping the scales at just 3.2 kg (7.05 lbs), this pre-preg carbon fibre and CNC-machined 6082 T6 aluminium hub construction slashes rotating mass at the rear axle — sharpening acceleration out of corners, improving braking response and reducing unsprung weight for more compliant suspension behaviour lap after lap.
Key Features
- Race-derived weight of 3.2 kg / 7.05 lbs — a dramatic reduction in rotating and unsprung mass for measurably faster acceleration and more precise handling
- Pre-preg carbon fibre rim bonded to a precision CNC-machined 6082 T6 aluminium hub — engineered for extreme structural integrity under sustained race loads
- DOT E and JWL certified — fully homologated for both track days and road use without compromise
- Extreme load ratings: 994.3 lbs / 451 kg radial load, 617 lbs / 280 kg static load, 772 Nm cornering load, 1,030 Nm torsional load
- Ultra-high-speed 90° aluminium racing valve with cap included as standard
- Available with steel or ceramic bearing options to suit road touring or all-out race applications
- 2-year manufacturer warranty
Construction & Engineering
The Mamba 7 TEK is built around BST's time-proven pre-preg carbon fibre layup process, where fibres are pre-impregnated with a precisely controlled resin matrix before being laid up and cured under controlled heat and pressure. The result is a rim with an exceptional strength-to-weight ratio that maintains dimensional stability under the cornering and braking loads generated by a high-powered superbike. The hub is machined from aerospace-grade 6082 T6 aluminium alloy, chosen for its excellent fatigue resistance and compatibility with carbon fibre co-efficients. Buyers can specify steel or ceramic bearings depending on application: steel bearings offer proven durability for mixed road and track use, while ceramic bearings reduce rotational friction further for dedicated race environments.
Track Performance & Road Homologation
Reducing rotating mass at the rear wheel is one of the highest-return modifications available to a sports rider. The Mamba 7 TEK delivers this benefit without sacrificing the legal compliance required for road registration — DOT E and JWL approvals cover both track and public road use. The wheel is supplied in the original OEM fitment size as standard; alternative dimensions are available on request, making it straightforward to explore alternative tyre profiles for specific circuit setups.
