DescriptionThe whole story▼
Few wheels carry the pedigree of the BST Diamond Tek — a front wheel whose carbon fibre architecture and race-proven load ratings have earned it a place on the world's most demanding Superbike circuits and the finest road machines alike. Engineered specifically for the Aprilia RSV4, RR, RF and 1100 Factory from 2015 to 2020, it combines extraordinary lightness with a finish range that lets you tailor its appearance to your build with the same precision BST applies to its construction.
Key Features
- Weighs just 2.50 kg (5.51 lbs) — a significant unsprung mass reduction that sharpens steering response and quickens direction changes perceptibly on both road and track.
- Rim shell formed from pre-preg carbon fibre for an optimal fibre-to-resin ratio, delivering consistent strength with minimal weight.
- Hub CNC-machined from 6082 T6 aluminium billet, providing the precise geometry and durability demanded by high-performance street and race use.
- Independently certified to DOT E and JWL standards, confirming full road legality alongside track capability.
- Structural load ratings that exceed everyday riding demands: radial load 357 kg, cornering load 543 Nm, torsional load 568 Nm.
- BST Ultra-High-Speed 90° aluminium valve included as standard — engineered to retain tyre pressure integrity at the rotational speeds the RSV4 platform achieves.
- Backed by a two-year manufacturer's warranty.
Design, Finish and Heritage
The Diamond Tek name is more than a marketing term — it reflects BST's distinctive woven carbon aesthetic, a pattern refined across two decades of supplying wheels to MotoGP and World Superbike teams. Every rim begins as a hand-laid pre-preg carbon shell, cured under controlled heat and pressure to eliminate voids and guarantee consistency between units. The result is a surface quality that looks as purposeful in a paddock garage as it does in a private collection.
The finish options extend well beyond the natural carbon weave. Alongside the classic high-gloss and satin-matte carbon presentations, BST offers a Forged Carbon Finish for those who prefer a different texture character, and a range of solid colour anodised finishes — blue, red, green, gold, silver and orange — as well as Schwarz Ink (Black Ink). Each option is applied with the same care taken over the structural laminate, so the wheel presents as a cohesive whole rather than a painted afterthought.
Performance on Road and Track
Reducing unsprung and rotating mass at the front end has a disproportionate effect on how a motorcycle feels to ride. The BST Diamond Tek front wheel lightens the gyroscopic forces the front assembly generates, making the RSV4's already responsive steering even more immediate. Under braking, the reduced rotational inertia means the wheel decelerates faster, allowing the suspension to work more efficiently and giving the rider a cleaner signal through the handlebars. These are gains that data can confirm and that most experienced riders feel within the first few corners.
The wheel ships in the standard fitment size for the Aprilia RSV4 / RR / RF / 1100 Factory application. Alternative sizes are available on request — contact Inter-Pace to discuss your specific requirements.
