BST Diamond Tek Carbon Rear Wheel Aprilia RSV4 / RR / RF / 1100 Factory (2015–2020)

Engineered for riders who refuse to compromise, the BST Diamond Tek carbon rear wheel brings genuine racing-grade construction to the Aprilia RSV4 platform. Every gram of unsprung weight saved translates directly into sharper turn-in, quicker acceleration and more communicative handling — and at just 4.0 kg, this wheel makes that difference tangible from the first corner.

Key Features

• Pre-preg carbon fibre construction delivers exceptional stiffness-to-weight ratio alongside a finish that stands apart from cast or forged aluminium alternatives.
• Hub machined from 6082 T6 aluminium alloy — robust, corrosion-resistant and precisely engineered to accept the RSV4 drivetrain without modification.
• DOT E and JWL certified, confirming the wheel has been independently tested to the highest international standards for road and track use.
• Radial load rating of 445 kg, lateral load of 711 Nm and torsional load of 995 Nm — load figures that exceed the demands of aggressive road and circuit riding.
• BST Ultra-High-Speed valve included: 90-degree aluminium valve with cap, designed for tubeless fitment and high-speed stability.
• Available in a wide range of finishes — from high-gloss and satin-matte carbon to solid colours and the distinctive Forged-Carbon and Black Ink options — so the wheel complements your RSV4's livery rather than dictating it.
• Two-year manufacturer's warranty as standard.

Build Quality and Materials

BST's Diamond Tek series is built around aerospace-grade pre-preg carbon fibre, a material that is laid up under controlled temperature and pressure rather than simply wrapped or wet-laminated. The result is a consistent, void-free structure that maintains its integrity under the cyclical stresses of hard braking, lateral cornering loads and drive torque. The 6082 T6 aluminium hub is machined to tight tolerances, forming the interface between carbon rim and Aprilia driveline with no compromise on rigidity or fit.

At 8.82 lbs (4.0 kg) the Diamond Tek rear wheel represents a meaningful reduction in unsprung and rotating mass compared with a standard cast wheel. Reduced rotational inertia allows the engine to accelerate the wheel more freely, shortening drive out of corners and reducing the gyroscopic effect that resists direction changes. Riders notice the difference not as a raw number on a data sheet but as a bike that feels lighter, more agile and more responsive to input.

Road and Track Performance

The Diamond Tek rear wheel is homologated for public road use via DOT E and JWL certification, so there is no need to swap wheels between road and track days. Its load ratings — 445 kg radial, 711 Nm lateral and 995 Nm torsional — are not theoretical peaks but tested thresholds that place the wheel well within safety margins even under the sustained stresses of circuit riding. The BST 90-degree aluminium valve eases tyre pressure checks and inflation in the pits without removing bodywork.

Fitment and Compatibility

This rear wheel is designed specifically for the following Aprilia models:

• Aprilia RSV4 (2015–2020)
• Aprilia RSV4 R (2015–2020)
• Aprilia RSV4 RR (2015–2020)
• Aprilia RSV4 RF (2015–2020)
• Aprilia RSV4 1100 (2019–2020)
• Aprilia RSV4 1100 Factory (2019–2020)

The wheel is supplied in the original fitment size. Alternative sizes — 4.5 x 17, 5.0 x 17, 5.5 x 17, 6.0 x 17 and 6.25 x 17 inches — are available on request. Choice of steel or ceramic bearings is available at the time of order.
