The GP TEK wheels are for competition or race use only

The GP TEK front wheel weighs only 3.75 lb. (1.7 kg) and the rear wheel is 5.29 lb. (2.4 kg) (depending on fitment), constructed with specialized carbon fiber specifically selected for enhanced cornering stiffness. The hubs are made using 6000 grade aircraft aluminum; the fasteners are grade 5 titanium; RFID tag traceability throughout its lifespan; and a specialized coating between the tire and rim that improves tire changing routines.

For motorcycle racing enthusiasts, there aren't many feelings that equal the excitement of running laps on a racetrack at their bikes' performance limit. And while race tracks were once only accessible to race-prepared bikes, today many bike clubs and some professional riding schools allow riders to learn more about high performance riding as they run their street bikes (with relatively few modifications) on the same tracks as sponsored racers. The BST GP TEK wheels were designed with MotoGP and MotoE in mind, BST's mission was simple, design the lightest-weight motorcycle wheel possible. Light-weighting involves the use of advanced materials and engineering methods to enable structural elements to deliver the same, or enhanced, technical performance while using less material. It also represents an effective way to reduce energy consumption while enhancing performance. Note for Ducati owners, due to the unique design of the GP TEK wheel, it is not possible to manufacture it for single sided, rear wheel application, therefore BST is developing a new wheel named Star TEK that will be the answer for Ducati applications. Look for the all new Star TEK at the end of the year.

For drag racing enthusiasts, the GP TEK wasn't built for you, although we know it will end up at the dragstrip. If you decide to install these on your drag bike, we want you to know that you do so at your own risk. BST feels confident in the strength of the GP TEK for loads experienced in track racing but coming down at over 100 mph on a hard wheelie is not what the GP TEK wheel was designed for. For drag racing application we recommend the 7 TEK.

Performance

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.

Design

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.

Manufacturing

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.

About BST

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 multiple national championships. BST has sold more than 50,000 carbon fiber wheels around the world.

Warranty

Brock's Logo Sticker

The Brock's logo sticker, as shown in the gallery images, are only used for display purposes and are not part of the wheel. If you are a racer that is interested in contingencies please ask to have the logo stickers applied.

Mounting Tires to Carbon Rims

Brocks Performance's engineering department guides you through the installation process and shows you how easy it is to install tires on the BST Carbon Fiber lightweight rims.

For best result, we recommend the use of AGS Ru-Glyde Lubricant which will protect beads against scuffing during mounting-assure proper bead seating on rim and protect against tire slippage after mounting.

Worldwide Bearings

All BST wheels come standard with steel bearings from Worldwide Bearings. For optimum performance, we recommend upgrading to WWB ceramic bearings. Click here to learn more about the performance advantages of ceramic bearings vs. steel.

Sprockets

Brock's Performance 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.

90-Degree Valve Stems

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 311 mph.

Testing

BST products have undergone decades of research, development, testing and the most stringent certifications processes. BST wheels exceed the performance requirements of all industry standard tests such as SAE and TÜV, and meet even more stringent quality requirements for OEM wheels.

BST wheels have been proven internationally at every level of FIM Grand Prix roadrace competition and in winning 12 championship titles around the world.

Anti-Slip Coating

To help reduce tire slip during drag-strip launches, all BST wheels 6.25" and wider come standard with BST's exclusive Ultra-High-Speed (UHS) Coating technology, a mixture of chemical adhesive and abrasives which create a sandpaper-like surface to reduce tire slippage on the rim. This process, used successfully in MotoGP racing since 2005, was developed to combat front-tire slippage during hard braking.
