DescriptionThe whole story▼
Every fraction of a second on track or a winding B-road is shaped by what spins at the front axle. The BST Star Tek carbon front wheel is built from prepreg carbon in a one-piece monocoque structure, combining CRBNX technology with a BST Ultra-High-Speed aluminium spider to deliver extraordinary stiffness at a recorded weight of approximately 2.4 kg — a transformation in rotating mass that your Aprilia RSV4, RR, RF or 1100 Factory (2015–2020) will communicate back through every corner entry.
Key Features
- One-piece monocoque prepreg carbon construction with CRBNX technology for exceptional stiffness-to-weight ratio
- BST Ultra-High-Speed aluminium spider integrated into the carbon shell for torsional precision at high lean angles
- Every wheel individually CT-scanned and TÜV-certified before leaving the factory — zero compromise on quality assurance
- Tested to TÜV 287 StVZO and JASO T203-85, including 1,000,000 bending and torsion cycles, a 6,000 km radial load run, and a radial impact test with residual pressure retention
- Fourteen finish options — from standard gloss exposed carbon to satin, matte, Candy and Solid colours — so aesthetics match performance
- Approved maximum load rating of 155 kg and backed by a two-year manufacturer's warranty
Construction & Materials
BST's Star Tek series represents the pinnacle of the brand's carbon wheel engineering. The monocoque body is laid up from aerospace-grade prepreg carbon fibre and cured under controlled heat and pressure. CRBNX technology refines the fibre orientation to maximise in-plane stiffness, which means the wheel resists flex under hard braking and lateral cornering loads without adding a single gram of unnecessary material. The aluminium ultra-high-speed spider is bonded and precisely located within the carbon structure, handling the hub interface loads while the carbon rim provides a perfectly true, aerodynamically efficient tyre seat.
The result is a front wheel that weighs approximately 2.4 kg — a significant reduction over the OEM item — with all the structural integrity a TÜV-certified component demands. ISO-certified production processes govern every stage, and the individual CT scan performed on each finished wheel means internal voids or delaminations are caught before the wheel ever sees a tyre.
Performance on Road & Track
Reducing rotating unsprung mass at the front axle sharpens steering response in a way that chassis geometry adjustments alone cannot replicate. Turn-in becomes crisper, mid-corner line corrections need less input, and the front tyre's contact patch loads with greater consistency because the wheel's moment of inertia is so much lower. Riders who have made the switch routinely describe the Aprilia feeling alive in a way that surprises them even after years on the standard wheel. Whether you are chasing lap times at a circuit or threading an alpine pass, the BST Star Tek front wheel makes the RSV4's already exceptional chassis feel sharper and more communicative.
Fitment & Compatibility
This wheel is engineered to fit the following Aprilia models as a direct OEM replacement:
- Aprilia RSV4 (2015–2020)
- Aprilia RSV4 R (2015–2020)
- Aprilia RSV4 RR (2015–2020)
- Aprilia RSV4 RF (2015–2020)
- Aprilia RSV4 1100 Factory (2015–2020)
Two bearing options are available at the time of ordering: steel bearings for standard road and track use, or ceramic bearings for riders seeking the lowest possible friction and maximum bearing longevity under sustained high-speed loads. Please confirm your model year and current wheel specification before ordering.
