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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePre-preg carbon fibre construction delivers exceptional stiffness-to-weight ratio alongside a finish that stands apart from cast or forged aluminium alternatives.\u003c\/li\u003e\n\u003cli\u003eHub machined from 6082 T6 aluminium alloy — robust, corrosion-resistant and precisely engineered to accept the RSV4 drivetrain without modification.\u003c\/li\u003e\n\u003cli\u003eDOT E and JWL certified, confirming the wheel has been independently tested to the highest international standards for road and track use.\u003c\/li\u003e\n\u003cli\u003eRadial 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.\u003c\/li\u003e\n\u003cli\u003eBST Ultra-High-Speed valve included: 90-degree aluminium valve with cap, designed for tubeless fitment and high-speed stability.\u003c\/li\u003e\n\u003cli\u003eAvailable 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.\u003c\/li\u003e\n\u003cli\u003eTwo-year manufacturer's warranty as standard.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eBST'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.\u003c\/p\u003e\u003cp\u003eAt 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.\u003c\/p\u003e\u003ch2\u003eRoad and Track Performance\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis rear wheel is designed specifically for the following Aprilia models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2015–2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 R (2015–2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2015–2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2015–2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 (2019–2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2019–2020)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe wheel is supplied in the original fitment size.
