DescriptionThe whole story▼
Built without compromise for competition, the BST GP TEK carbon wheel set is engineered specifically for the Aprilia RSV4, RSV4 R, RSV4 RR and RSV4 1100 Factory (2021–2026). At just 1.7 kg front and 2.4 kg rear (without bearings and spacers), these are among the lightest motorcycle wheels available for this platform — every gram saved here translates directly into reduced unsprung and rotational mass, sharper turn-in and faster lap times. Note: GP TEK wheels are designed exclusively for competition and track use.
Key Features
- Race-weight construction: front wheel 3.75 lbs / 1.7 kg, rear wheel 5.29 lbs / 2.4 kg (both figures exclude bearings and spacers)
- Pre-preg carbon fibre rim paired with 6082 T6 aluminium hubs for an optimal balance of stiffness and shock resistance
- Titanium Grade 5 bolts, inserts and nuts throughout — no unnecessary mass, maximum corrosion resistance
- Carbon fibre inner spacers add structural rigidity while keeping weight to an absolute minimum
- DOT E and JWL certified for track use, backed by a 2-year manufacturer's warranty
- Ultra-high-speed 90° aluminium valves supplied complete with caps
Performance on Track
The GP TEK series represents BST's most focused racing wheel, conceived for riders who demand every advantage the rules allow. The pre-preg carbon fibre construction delivers exceptional hoop stiffness under braking and lateral loads without the weight penalty of a cast aluminium wheel, letting suspension work more efficiently and giving the rider cleaner, more predictable feedback through every corner. The 6082 T6 aluminium hub interfaces are precision-machined to exact tolerances, ensuring the wheel seats correctly every time — critical when tyres are being changed between sessions. Titanium Grade 5 hardware runs through the entire assembly: bolts, inserts and nuts are all sourced from the same aerospace-grade alloy, eliminating any weak point in the fastener package. The carbon fibre inner spacers complete the picture, reinforcing the spoke-to-hub junction without adding mass.
Finish & Customisation
The GP TEK wheel set is available in a range of finishes to suit your Aprilia's livery or personal preference: Gloss, Satin-Matt, Forged-Carbon, Solid Blue, Solid Red, Solid Green, Solid Gold, Solid Silver, Solid Orange and Black Ink. Bearing options span standard steel bearings and ceramic bearings for riders seeking to reduce friction and maintenance intervals at the highest level. The set is supplied in standard OEM sizes; alternative sizes are available on request.
