BST Carbon Fiber Wheels - complete set of front and rear wheels with sprocket carrier, valve stems, 6000 series hubs, stainless hardware The BST 5 spoke carbon composite wheel is made using the latest technology, materials and manufacturing processes. This lightweight and exceedingly strong wheel is suitable for both racing and street racing use. The wheels have been tested at Rim Technology, Eurotype Test Centre and German TUV, and passed all the tests for road certification. BST wheels are unique in that they are created as a single unit - not bonded together. BST wheels are unique - monococque (single unit) design with 5 hollow spokes and are suitable for both street and race use. BST wheels can save you anything between 40- 60% in weight over stock wheels, and more importantly, are designed to deliver the lowest Moment of Inertia - the critical factor that affects the performance of the bike and how fast it changes direction. 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 fibre that BST uses is a woven and unidirectional 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. 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 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. Typical wheel weights: 4.62 lbs Front 5.94 lbs Rear Note: BST wheels accept stock brake rotors but require a special sprocket with different bolt pattern and spacing. Stock sprockets will not fit. Aluminum angled valve stems, urethane cush drives, bearings and sprocket carrier are included. DOT approved. *We can't advertise our aggressive prices on BST Carbon wheels, but email us for a quote:jeff@vietsperformance.com Regularly $3850-3990
