CVO Models: If you are purchasing wheels for Harley-Davidson CVO’s, due to variations in the OEM wheels equipped on each model, please look over the engineered drawings for your desired wheel. CVO models equipped with 7-bolt rotors (Agitator / Slicer / Chisel) may still be compatible with the purchase of aftermarket rotors. See Brake Rotor pitch circle diameter (PCD) for details on rotor fitment
What's New for the R-Series?
BST announce their latest Carbon Fiber design, a wheel which has optimized the potential of carbon fiber for more extreme requirements. The result: a stronger wheel, optimized for anyone who is passionate about functionality and performance, on the track or open road. We took our standard 3.5" x 17" carbon fiber front wheel and added a newly designed rim flange that has been reinforced by 3mm, and then we added 1mm of thickness around the rim and spoke joints, the best part, the new R-Series increased in weight by an average of only 11 ounces!
Results from the JWL Certification Process for Impact Testing:
JASO T203 impact test rig at 5.9 inches, the new BST "R" Series passed at the following levels showing a 52.3% improvement over the standard wheel.
New "R" Series 3.5" x 17" Front Wheel:
1058 lbs @ 29 psi tire pressure
Standard 3.5" x 17" Front Wheel:
694 lbs @ 29 psi tire pressure

Weighing between 40 and 60 percent less than OEM wheels, BST wheels bestow sportbikes with sharper corner-carving abilities, faster acceleration, and quicker braking by weighing less than their production-bike counterparts. Lighter wheels are also easier for suspension systems to control over bumps and irregular surfaces, yielding more traction and unimpeded acceleration. Less rotating mass also equals less rider fatigue.
A lighter rear wheel is easier for the shock to control properly, which leads to superior power application and much higher trap speeds in competition and track days.
Using high-tech processes pioneered in the aerospace industry, BST wheels are manufactured in a single molding operation. This technique produces a wheel that is far superior in strength and much lighter than any aluminum or magnesium wheel, and one that is light and strong enough for racing and street use.
BST wheels are a unique monococque (single unit) design with hollow spokes. The end result is wheels with unsprung weight reduced 40-60 percent compared to stock wheels. This delivers the lowest possible moment of inertia, a critical factor that affects all aspects of motorcycle performance.
Maximizing the molecular and structural properties of carbon fiber, BST has reduced spoke and rim weight without compromising their strength. Mass is therefore concentrated in the hub, reducing rotational inertia. This results in quicker acceleration and braking, allowing faster corner entry and exit speeds.
BST designs the tooling, molds, wheel and hubs, then manufactures them in its state-of-the-art factory. Precision cutting machines, like those used in the aeronautical industry, ensure that the process is repeatable and meets the highest certification standards. BST uses only the finest “prepreg” carbon fiber, which is embedded in a top-secret resin matrix epoxy. Carbon-fiber layup is done in a dust-free and temperature-controlled “clean room.” The wheels are cured in a superheated steam oven, or autoclave, at 260 degrees and 85 psi. This produces the best material compaction and smoothest surface finish. Every step of this process is logged, the entire history of each wheel is stored and stamped with a unique serial number. To ensure the highest quality manufacturing processes and components, BST’s entire operation is managed under strict, new ISO 9002 standards.
Established in 1992, BST is based near Johannesburg, South Africa. BST engineers and manufactures the world's finest carbon fiber motorcycle components from wheels and frames to fuel tanks and fenders, to the highest international standards. The standard equipment wheels on Confederate and Norton motorcycles, BST was also chosen to provide wheels and produce the carbon-fiber frame on the radical MotoCyz project. On the world stage, BST wheels have been proven at every level of FIM Grand Prix roadracing competition and have won 12 national championships. BST has sold more than 8,000 carbon fiber wheels around the world.
BST Dealers offer service for all BST wheels, allowing faster repair of road or track damaged wheels.
All BST wheels come with a two-year, limited manufacturer’s warranty.
