The facts.
DescriptionThe whole story▼
When safety certification and outright performance must coexist, the BST Diamond Tek Carbon rear wheel sets the benchmark. DOT E and JWL certified to the most demanding international standards, this wheel delivers genuine racing technology to the Suzuki GSX-R 1000 (2017–2023) without a single compromise on structural integrity.
Key Features
- DOT E and JWL certified — independently tested and verified to meet the strictest international safety and load standards, giving you total confidence on road and track.
- Proven load ratings: 445 kg radial load, 711 Nm cornering load, and 995 Nm torsional load — engineered to withstand the forces generated by a litre-class superbike at full pace.
- Ultralight construction at just 4.0 kg (8.82 lbs), dramatically reducing unsprung mass for sharper steering response and faster acceleration.
- Pre-preg carbon fibre rim bonded to CNC-machined 6082 T6 aluminium hubs — aerospace-grade materials selected for maximum strength-to-weight ratio.
- Ultra-high-speed 90° aluminium valve with cap included as standard.
- Choice of steel or ceramic bearings to suit your riding style and environment.
- 2-year manufacturer's warranty for complete peace of mind.
Safety, Certification and Structural Integrity
Every BST Diamond Tek wheel undergoes rigorous third-party testing before it ever reaches a customer. The dual DOT E and JWL certifications are not marketing footnotes — they represent independent laboratory verification of radial, cornering, and torsional load capacity under conditions that replicate the most demanding real-world scenarios. For riders who push their GSX-R 1000 to its limits, whether on a public road or a circuit, that certified safety margin is the foundation everything else is built on.
The pre-preg carbon fibre construction ensures consistent fibre orientation and resin distribution throughout the rim, eliminating the weak points associated with wet lay-up processes. The result is a wheel that is simultaneously lighter, stiffer, and more resilient than cast aluminium alternatives.
Performance on Road and Track
Reducing unsprung mass is one of the most effective ways to improve a motorcycle's dynamic behaviour, and at 4.0 kg the Diamond Tek rear wheel achieves reductions that are simply not possible with conventional aluminium. The GSX-R 1000 responds with more precise turn-in, improved mid-corner stability, and noticeably faster acceleration thanks to lower rotational inertia. Whether you are chasing lap times or simply want a more engaging ride on your favourite road, the improvement is immediately felt.
The wheel is supplied in the original fitment size as standard. Additional sizes — 4.5
