DescriptionThe whole story▼
When every tenth of a second counts on track, the BST Diamond Tek carbon front wheel delivers the unsprung-mass reduction that transforms the Aprilia RSV4, RSV4 RR and RSV4 1100 Factory into a sharper, more responsive machine. At just 2.50 kg, this wheel strips rotational inertia from the front axle, giving you quicker turn-in, more faithful braking feedback and a handling balance that no aluminium wheel can match.
Key Features
- Extreme weight saving at 5.51 lbs / 2.50 kg — direct reduction in unsprung and rotating mass for measurably faster direction changes
- Pre-preg carbon fibre rim bonded to 6082 T6 aluminium hub — aerospace-grade construction that balances stiffness with impact resilience
- Certified for road and track use: DOT E and JWL homologated, so the wheel is equally at home at a circuit trackday or on public roads
- Proven load ratings: 357 kg radial load, 543 Nm cornering load and 568 Nm torsional load — engineered to handle the RSV4's power and braking forces without compromise
- BST Ultra-High-Speed valve included: 90-degree aluminium valve with cap, ready for high-speed use
- Available with steel or ceramic bearings — choose ceramic for the ultimate in friction reduction and longevity under hard use
- Two-year manufacturer's warranty for peace of mind on road and circuit alike
Racing-Grade Carbon Construction
BST's Diamond Tek process uses pre-preg carbon fibre layered and cured under controlled heat and pressure, producing a rim that is both lighter and stiffer than any cast or forged aluminium alternative. The 6082 T6 aluminium hub is precision-machined for an exact, rattle-free fitment on the RSV4's front axle. The result is a wheel that transmits tyre information to the rider with exceptional clarity — a genuine advantage when you are chasing lap times or reading a fast road.
Road and Track Performance
Reducing front unsprung mass on a high-performance superbike like the RSV4 1100 Factory improves suspension compliance, braking stability and mid-corner confidence simultaneously. The Diamond Tek wheel is supplied in the standard original equipment diameter of 17 inches. Three width options — 2.75 x 17, 3.5 x 17 and 3.75 x 17 — allow you to choose the profile that best suits your tyre preference and intended use. Additional sizes are available on request.
