DescriptionThe whole story▼
Engineered specifically for the Yamaha YZF-R1/M across the RN32, RN49 and RN65 generations, the BST Diamond Tek carbon rear wheel transforms the way your R1 feels from the very first corner. At just 4.0 kg, it reduces unsprung mass dramatically, rewarding you with an effortless, planted ride that remains composed mile after mile — whether you're threading traffic on a Sunday morning or chasing lap times at the circuit.
Key Features
- Weighs only 8.82 lbs / 4.0 kg — reduced unsprung mass sharpens steering response and noticeably lightens the bike's feel over long rides
- Pre-preg carbon fibre construction paired with CNC-machined 6082 T6 aluminium hubs for exceptional stiffness-to-weight ratio
- DOT E and JWL certified — engineered to withstand the most demanding road and track loads
- Rated to 445 kg radial load, 711 Nm lateral load and 995 Nm torsional load for confidence in every condition
- BST Ultra-High-Speed valve: 90-degree aluminium valve complete with cap
- Available with steel or ceramic bearing options to suit your riding style and performance goals
- 2-year manufacturer's warranty included
Precision Construction for All-Day Confidence
BST's Diamond Tek layup process uses aerospace-grade pre-preg carbon fibre, where each layer is precisely oriented for maximum stiffness exactly where the wheel needs it most. The result is a rim that absorbs road imperfections without flexing unpredictably — a quality that pays dividends on long-distance riding as much as on track day sprints. The CNC-machined 6082 T6 aluminium hub interfaces cleanly with the YZF-R1/M drivetrain, ensuring straightforward fitment and lasting dimensional accuracy.
Road and Track Performance
The reduction in rotational inertia brought by the Diamond Tek rear wheel means the R1/M accelerates more freely, changes direction with less effort, and returns sharper feedback through the chassis. Riders notice the difference not just in outright pace, but in the reduced fatigue that comes from a bike that communicates more clearly — a genuine comfort advantage over an extended ride or a full track day. Multiple finish options, from high-gloss carbon to Solid colour variants, allow you to personalise without compromising structural integrity.
