Hayabusa-based Motorcycle Breaks 300 MPH Barrier

When Suzuki launched the GSX1300R Hayabusa sportbike more than a decade ago, the bike was instantly recognized as the world's fastest production motorcycle, with a top speed of 188 to 194 mph (303 to 312 km/h). For most of us, that would be more than enough, but not for Bill Warner.

This past weekend, Warner became the first man to exceed 300 mph (483 km/h) riding a sit-on motorcycle, with a 311.94 mph (502 km/h) run on the 1.5-mile course, a video of this feat being available below this article.

Using a turbocharged, methanol-fueled Hayabusa-based racebike designed to provide 1,000 horsepower, Warner smashed his top-speed record of 278.6 mph (448 km/h) rolling on DOT-approved BST carbon-fiber street wheels.

“We wanted to make sure that we had enough strength to deal with the potential power output and centrifugal forces developed at these ridiculous speeds. Thanks to Bill’s testing, BST’s ILR wheels are now available for race and street use to consumers,” said Brock's Performance President Brock Davidson.

The record-setting bike was set up with products and technical support from the following companies: AiM Sports dataloggers, Alisyn oil, APE, ARP fasteners, Brock’s Performance, BST wheels, Continental tires, Crower rods, Dainese leathers, Full Spectrum Power batteries, Garrett Turbo, Heads Up Performance, Injector Dynamics, Knecum Performance, Larry Forstall Racing, M&W ignitions, Marine Crankshaft, McIntosh Machine and Fab, Millennium Technologies, MTC Engineering, NLR boost controller, Öhlins suspension, R&D Transmissions, RCC Turbos, Spiegler, Swain Tech Coatings, T1 Racing, Tial, Web Cam, Weimer Welding, Weldon pumps, World Wide Bearings and Zip Sensors.
