 BST wheels are unique - monococque (single unit) design with 5 hollow spokes and are suitable for both street and race use.
BST wheels will save you anything between 40- 60 per cent in weight, and more importantly, are designed to deliver the lowest Moment of Inertia - the critical factor that affects the performance of the bike.
Because BST can engineer with carbon fibre and maximise on its properties of high strength and low weight, we have reduced the weight in the spokes and rim without compromising strength. The weight is therefore concentrated in the hub, which means that rotational inertia is reduced, making the bike easier to handle, and allowing you to accelerate quicker and brake later. So not only is the wheel lighter, but it is engineered for maximum performance.
The entire process is managed under ISO9002 standards. BST design the tooling, moulds, wheel and the hubs and manufacture them onsite. Cutting machines such as those used in the aeronautical industry ensure that the process is guaranteed and repeatable to certified high standards. Layup is done in a clean room (dust-free, temperature controlled).
The wheels are cured in an Autoclave at 125 degrees C and 6 bar of pressure. This ensures the best compaction and surface finish.
Every step of the process is logged and the entire history of each wheel is stored.
The carbon fiber that BST uses is a woven and uni-directional format, and is embedded in a resin matrix made from toughened epoxy. Pre-preg is used as the machine application of the specific resin systems ensures the most controlled and even application and therefore the highest quality material for use in the BST wheels.
Features:
- TUV certification for wheels (GSXR1000 front and rears, Ducati 916-998 series and 748 fronts and rears, others in process)
- DoT and JWL compliant
- Aerospace FAR25 qualified materials
- Manufacturing facility is TUV certified, and ISO 9002 compliant
- Complete traceability in manufacturing process and materials used including the hubs
- Manufacturing process allows for full identification (each has its own Serial No) and traceability (based on the process used for critical parts in the aerospace industry)
- Nesting and cutting machines are the same as those used in the aerospace industry - each wheel pattern is cut and the part is numbered simultaneously guaranteeing correctness and uniformity
- Layup of wheels is done in a Clean room (dust free, temperature controlled)
- Wheels passed all tests for road certification carried out by Rim Technology (UK government certified facility) and Investmech test center.
- Corner fatigue carried out as specified in BS. AU. 50.
- Radial fatigue carried out as specified in BS. AU. 50.
- Torsional fatigue carried out as specified in BS. AU. 50.
- Impact test carried out as specified in JWL
The SECRET WEAPON: Club racers in Europe are fitting BST CF wheels on their 600cc bikes and competing with 1000cc bikes.
Racers are reporting lap times of 2.5-3.0 seconds faster with Carbon wheels over the stock wheels and 1.5 seconds faster over magnesium wheels. Drag racers are reporting .2 seconds in the quarter mile.
Some racers are foregoing additional engine and brake modifications and putting the extra money into these wheels.
“If you could compare both these bikes side by side … there would br no way to catch the BST-wheeled machine. The difference is small to begin with, but the carbon wheels get the bike to 80kph in one metre less than the standard bike. It then builds with time and by 95kph the BST wheels have take 3.5 metres less, at 160kph they have a 13 metre advantage and by 240kph they are a full 108 metres ahead.”

Typical weights:
Weight:
Street Front:
2.1 - 2.4 kg, depending on motorcycle
(complete with hub, bearings, spacers and all fittings).
Race Front:
1.9 - 2.1 kg, depending on motorcycle
(including hub, bearings, spacers and all fittings).
The BST wheels are among the strongest on the market (at the Munich Intermot show, BST representatives bounced the wheels on the ground thoughout the duration of Intermot to show they can take it.
Note: BST wheels uses the OEM rotors but require a special sprocket. The OEM sprocket will not fit. Aluminum angled valve stems, urethane cush drives, bearings and sprocket carrier are included with all double sided swingarm rear wheels.
Part of the TUV requirements require that manufacturing consistentcies are in place. BST wheels are serial numbered and tested through out the building process.
Benefits of Carbon Fiber wheels:
Lower unsprung mass brings down rotational inertia resulting in quick and responsive steering and acceleration. Longer product life—carbon fiber is a fatigue-free material, carbon fiber composite is a damage tolerant material, and carbon fiber is corrosion-free. Attractive woven finish gives the wheels, and your bike, a beautiful, full-race look. Since the weight saving comes from the spokes and the rim, the mass of the wheel is concentrated in the hub to the benefit of rotational inertia. Because our wheels offer a substantial reduction in flywheel and gyroscopic effects, the motorcycle can accelerate, corner and brake faster. In particular, the reduced gyroscopic effect allows for faster directional changes, which makes the motorcycle far more sensitive to the rider’s inputs. You will find yourself riding faster and further with less effort—for you and your engine. Don't confuse these wheels with the first generation carbon wheels or simple carbon fenders that you see. BST wheels are all one-piece, pre-preg construction. They are "cooked " in an autoclave for over four hours under 6 bar of pressure, removing all excess resins and providing the strongest, lightest wheel construction.
They are easier to safely mount tires on than a painted rim, as there is no paint to chip off. BST carbon fiber wheels outperform magnesium and aluminum in all stress tests. We have never had a wheel returned due to damage by a tire machine used properly.
