Recommends Vortex sprockets for all BST applications but any sprocket that has the following measurements will work: 5 (10mm holes) with a PCD (Pitch Circle Diameter) of 100mm and a sprocket ID of 76mm. Based in the USA, Vortex has been manufacturing top quality racing components since 1995. Owned and operated by motorcycle racers, they focus on absolute quality. Each of their race components are made to the tightest tolerances with the best quality materials for the application. Vortex tests on the track with direct feedback from top professional race teams worldwide.

The hubs are attached to the wheels using a unique fastening system that combines high-tech aerospace fasteners, mechanical locking mechanisms and super-high-strength aerospace adhesive. In the event of rim damage the hub can typically be salvaged and the carbon rim replaced at a substantial savings over purchasing a new wheel. (Except on BST wheels with forged carbon hubs)
All BST wheels come with aluminum 90-degree valve stems that are not only easy to access, but keep centrifugal force from opening their Schrader valves and deflating tires during high-speed operation. Track tested up to 274 mph.
BST products have undergone decades of research, development, testing and the most stringent certifications processes. They’ve been flogged at Rim Technology, Eurotype Test Centre and have passed all lab and street tests for certification from Germany’s TüV to the U.S. Department of Transportation, with flying colors.
BST wheels have been proven internationally at every level of FIM Grand Prix roadrace competition and in winning 12 championship titles around the world.
