DescriptionThe whole story▼
At just 2.4 kg without bearings and spacers, the BST GP TEK Carbon rear wheel is one of the lightest competition hoops available for the Aprilia RSV4 family — a direct, measurable reduction in unsprung and rotating mass that sharpens steering response and transforms how the bike feels at the limit. Built exclusively for competition use, every gram saved here is a gram your chassis and suspension can manage with less compromise.
Key Features
- Pre-preg carbon fibre rim weighing only 5.29 lbs / 2.4 kg (without bearings and spacers) for dramatically reduced rotating mass
- CNC-machined hub in 6082 T6 aluminium — precision tolerances and strength where the loads are highest
- Titanium Grade 5 bolts, inserts and nuts throughout for a hardware package that matches the wheel's competition intent
- Carbon fibre inner spacer adds rigidity while keeping weight to an absolute minimum
- DOT E and JWL certified for track use — independently verified structural integrity
- BST Ultra-High-Speed valve: 90° aluminium valve stem with cap included
- 2-year manufacturer's warranty for peace of mind even on track
Construction and Engineering
BST's GP TEK series exists at the top of the company's wheel hierarchy, combining pre-preg carbon fibre rim construction with aerospace-grade metalwork. The rim itself is built from pre-preg carbon fibre — a process where resin and fibre are combined under controlled conditions before curing, producing a consistently high-quality laminate with no trapped air or voids. The hub is machined from 6082 T6 aluminium billet, a grade chosen for its excellent strength-to-weight ratio and resistance to fatigue under cyclic loading. Titanium Grade 5 fasteners are used at every structural joint, eliminating the weight penalty of steel without sacrificing clamping force or reliability. A carbon fibre inner spacer completes the assembly, maintaining concentricity and stiffness between hub and rim under hard cornering and braking loads.
Competition Use
The GP TEK wheels are designed and rated exclusively for competition and race use. The load ratings — 283 kg radial, 250 kg static, 720 Nm cornering and 1,043 Nm torsional — reflect a wheel engineered to absorb the sustained demands of track riding rather than road use. Riders who compete at club or national level on Aprilia RSV4-based machinery will find the GP TEK rear wheel delivers a tangible improvement in overall bike balance and agility, with the mass reduction felt most clearly during direction changes and mid-corner adjustments. This is not a cosmetic upgrade; it is a performance component with a measurable effect on lap times.
