BST STAR TEK Carbon Wheel Set – Aprilia RSV4 / RR / RF / 1100 Factory (2015–2020)

Every fraction of unsprung and rotational mass removed from your Aprilia RSV4, RR, RF or 1100 Factory translates directly into sharper turn-in, reduced braking distances and explosive drive out of corners. The BST STAR TEK carbon wheel set achieves exactly that through TÜV- and JASO-certified monocoque Prepreg-carbon construction — verified safe, devastatingly light, and built to race-winning standards.

Key Features

• TÜV- and JASO-certified load testing — 1,000,000 bending and torsion cycles, 6,000 km radial load endurance, and a radial impact test with retained residual air pressure, giving you documented, third-party-verified safety on road and track
• CT-scanned and individually inspected — every single wheel is CT-scanned and visually inspected before dispatch, ensuring zero internal defects reach the customer
• ISO-certified manufacturing with a 2-year warranty — production quality controlled at every stage, backed by a comprehensive two-year guarantee
• Monocoque CRBNX-technology Prepreg-carbon construction paired with a BST Ultra-High-Speed aluminium spoke centre — maximum structural rigidity at minimal rotational weight
• Front wheel approx. 2.4 kg with a 155 kg load rating; rear wheel approx. 2.2–2.75 kg (depending on specification) with a 280 kg load rating
• Wide finish selection — standard gloss carbon, satin, matte, seven Candy colours and six Solid colours, plus Steel or Ceramic bearing options

Engineering and Construction

The STAR TEK design centres on BST's monocoque manufacturing method, in which the entire carbon structure is formed as a single integrated unit. There are no bonded joints or mechanical fasteners within the carbon shell itself — the result is a wheel that distributes stress evenly and resists the cyclical fatigue that multi-piece constructions are susceptible to over time.

The CRBNX-technology Prepreg-carbon used in these wheels is a high-modulus material layered and cured under controlled pressure and temperature, giving the finished wheel a fibre-to-resin ratio and void content that conventional hand-laid carbon cannot match. The BST Ultra-High-Speed aluminium spoke centre is machined to interface with this shell, keeping total mass remarkably low while handling the torque loads a Tuono-derived V4 produces at the rear hub.

Safety and Testing

BST subjects every STAR TEK wheel to a comprehensive test programme before it leaves the factory. Structural integrity is confirmed through 1,000,000 bending and torsion cycles to TÜV and JASO standards. Radial durability is validated over 6,000 km of simulated radial loading. An additional radial impact test verifies that the wheel retains air pressure after a kerb-strike event — critical for real-world road and track riding. Following these structural tests, each individual wheel undergoes CT scanning and a full visual inspection so that any internal anomaly, however small, is caught before the wheel is approved for sale.

On Road and Track

Reducing rotational inertia transforms how the RSV4 platform feels in transitions. Lighter wheels require less effort to change direction, so flicking between apices demands less physical input and the bike responds more immediately to steering commands. The same reduction in gyroscopic effect also allows the suspension to track surface irregularities more faithfully, improving mid-corner stability and tyre contact. On the road, the lighter unsprung mass translates into a more composed ride over imperfect surfaces.
