BST RAPID TEK Carbon Rear Wheel Kawasaki ZX-10R (2021–2026)

Shaped by decades of motorsport engineering and finished to a standard that turns heads in the paddock and on the road, the BST RAPID TEK carbon rear wheel for the Kawasaki ZX-10R (2021–2026) represents the pinnacle of what a production wheel can be. At just 3.20 kg, it strips rotational mass from one of the most demanding points in the drivetrain, translating directly into sharper acceleration, more responsive handling and a ride quality that no cast alloy wheel can match.

Key Features

• Ultralight construction at 7.05 lbs / 3.20 kg — reduced rotational mass for faster acceleration and more agile direction changes
• Pre-preg carbon fibre rim paired with a CNC-machined 6082 T6 aluminium hub for the ideal balance of rigidity and vibration damping
• DOT E and JWL certified — fully approved for road and track use with no compromise
• Engineered to withstand radial loads of 994 lbs / 451 kg, static loads of 617 lbs / 280 kg, cornering loads of 772 Nm and torsional loads of 1,030 Nm
• Ultra-high-speed 90° aluminium valve with cap included as standard
• Backed by a two-year manufacturer's warranty

Heritage, Design and Finish

BST — Black Stone Tek — has been setting the benchmark for carbon fibre wheels in premium motorsport since the early 2000s. The RAPID TEK name reflects both the manufacturing philosophy and the aesthetic intent: a wheel that looks as purposeful as it performs. The pre-preg carbon construction means every layer of fibre is precisely oriented and resin-impregnated under controlled conditions before cure, producing a rim that is consistent, stiff and visually striking in a way that no post-process carbon finish can replicate.

The finish options — from the deep lustre of the high-gloss carbon to the understated sophistication of the satin-matte, through to the bold solid colours and the textured forged-carbon finish — allow every ZX-10R owner to build a wheel that is unambiguously their own. Whether you are building a track-day weapon or a road machine that refuses to blend in, the RAPID TEK offers a finish to match the vision.

Performance on Road and Track

The reduction in unsprung and rotational mass that the RAPID TEK delivers is not incremental — it is transformative. The ZX-10R's inline-four makes its best power at the top of the rev range, and a lighter rear wheel allows that power to translate into forward motion more efficiently, with the added benefit of suspension that can react faster to surface changes because it has less mass to control. On circuit, this means lap times. On road, it means a level of engagement that is difficult to put into words until you have ridden it back-to-back with a conventional alloy wheel.

The wheel is supplied in the standard OEM size as default. Alternative dimensions are available on request.

Fitment and Compatibility

This BST RAPID TEK carbon rear wheel is engineered specifically for the Kawasaki ZX-10R covering model years 2021 through 2026. Available with a choice of steel or ceramic bearing specification to suit road or competition use.
