DescriptionThe whole story▼
Constructed from aerospace-grade pre-preg carbon fibre and anchored by a precision CNC-machined 6082 T6 aluminium hub, the BST Rapid Tek front wheel represents the highest standard of lightweight wheel engineering available for the Aprilia RSV4 family. At just 2.75 kg, it slashes rotational mass to deliver sharper turn-in, more responsive steering and genuinely perceptible gains in acceleration and deceleration — on the road and on circuit alike.
Key Features
- Ultralight construction at 6.06 lbs / 2.75 kg — reduced rotational inertia for faster, more precise steering
- Pre-preg carbon fibre rim paired with a CNC-machined 6082 T6 aluminium hub for an exceptional strength-to-weight ratio
- DOT E and JWL certified — fully homologated for road and track use
- Rated to 855 lbs / 388 kg radial load, 341 lbs / 155 kg static load, 577 Nm cornering load and 543.9 Nm torsional load
- Ultra-high-speed 90° aluminium valve with cap included as standard
- Choice of bearing specification: steel or ceramic bearings
- 2-year factory warranty
Build Quality and Materials
BST's Rapid Tek construction process uses high-strength pre-preg carbon fibre throughout the rim, a material selected for its exceptional stiffness, fatigue resistance and consistent mechanical properties under the sustained loads of hard riding. Unlike wet-lay alternatives, pre-preg carbon delivers tighter fibre-to-resin ratios and repeatable quality in every unit. The hub is machined from 6082 T6 aluminium alloy — a grade chosen for its high tensile strength and corrosion resistance — and integrates seamlessly with the carbon rim via a bond engineered to meet DOT E and JWL certification standards. The available ceramic bearing upgrade further reduces parasitic friction and extends service intervals for riders who demand the very best from every component.
On Road and on Track
Reducing unsprung and rotational mass at the front axle is one of the most effective single-component upgrades a rider can make. The Rapid Tek front wheel allows the suspension to respond faster to surface irregularities, keeps the tyre in contact with the road through more of each corner and lightens the steering without requiring any chassis adjustment. Whether you are pressing through technical road sections or fighting for lap time at a track day, the tangible reduction in gyroscopic effect makes the RSV4's already razor-sharp handling even more direct. The wheel is supplied in the standard original fitment size as standard; alternative dimensions are available on request.
