DescriptionThe whole story▼

Engineered for riders who demand total confidence from dawn commute to circuit session, the BST Mamba 7 TEK carbon front wheel delivers a riding experience that feels immediately, unmistakably right — a wheel that sits perfectly in your hands through every corner. Weighing just 2.75 kg, it strips rotational mass from the Yamaha YZF-R1/M front end and returns a front wheel that turns in crisply, tracks with precision, and never fights back when you're threading through a long, committed sequence of bends.

Key Features

  • Ultra-low rotational mass at just 6.06 lbs / 2.75 kg, for noticeably sharper turn-in and reduced rider fatigue on long days in the saddle.
  • Pre-preg carbon fibre rim construction for an ideal balance of strength, stiffness and ride comfort that a metal wheel simply cannot match.
  • CNC-machined 6082 T6 aluminium hub for dimensional accuracy and long-term durability under sustained load.
  • Dual road and track certification — DOT E and JWL approved — so the wheel moves seamlessly between street use and circuit days without compromise.
  • Racing-specification 90-degree ultra-high-speed aluminium valve with cap included as standard.
  • Two-year manufacturer's warranty for peace of mind on every ride.

Construction & Performance

BST's Mamba 7 TEK uses pre-preg carbon fibre throughout the rim section — the same process applied to aerospace and Formula 1 components. Pre-preg means each layer of fibre arrives pre-impregnated with resin at a controlled ratio, then cured under heat and pressure to eliminate voids and inconsistencies. The result is a rim that is not only light but extraordinarily stiff in the radial and lateral directions that matter most when hard braking and mid-corner loading are at their peak.

The 6082 T6 aluminium hub is CNC-machined to tight tolerances and connects the carbon rim to the motorcycle's axle, bearings and brake disc mounting with the rigidity expected of a performance component. The transition between rim and hub is engineered to distribute stress evenly, protecting the carbon structure across the full load spectrum that track and road riding demands.

Load Ratings

Despite its minimal weight, the Mamba 7 TEK front wheel is rated to handle serious structural demands: a radial load of 855.4 lbs / 388 kg, a static load of 341 lbs / 155 kg, a lateral cornering load of 577 Nm, and a torsional load of 543.9 Nm. These figures are the product of rigorous testing and underpin the wheel's dual street and circuit approval.

Fitment & Compatibility

This front wheel is supplied in the original factory size and fits the following Yamaha models directly:

  • Yamaha YZF-R1 / YZF-R1M — RN32 (2015–2016)
  • Yamaha YZF-R1 / YZF-R1M — RN49 (2017–2020)
