Buell Motorcycle Company announced today at its winter dealer convention in Grapevine, Texas that it plans to produce and sell 50 non-street-legal racebikes for privateer racers and dealership-based race teams called the Firebolt XB-RR. And these will not simply be Firebolts with the lights and turn signals removed at the factory.

The Firebolt XB-RR is expected to produce over 150 horsepower and over 100 ft.-lbs. of torque at the crankshaft, to weigh approximately 362 pounds dry, to have its engine be durable enough to race an entire season with only routine maintenance and be versatile enough to race in several different classes from AMA Formula Xtreme to American Sportbike Racing Association (ASRA, formerly known as Formula USA) Thunderbike and several other club and endurance racing classes.

The bike will come with Ohlins suspension, wind-tunnel developed carbon-fiber bodywork, an eight-piston front brake caliper developed specifically for the application by Nissin, and more. In addition, every single part on the bike, plus optional parts, will be available for anyone to order out of a catalog at any Buell dealership.

Buell will back the Firebolt XB-RR with parts and technical support at all AMA and most ASRA rounds and with an expanded cash contingency program.

A short production run of Firebolt XB-RRs will happen in February, and full production is scheduled to begin in April 2006. Suggested retail price will be $30,995.

More about the Buell Firebolt XB-RR, including technical specifications and the story behind the bike, will appear in the March 2006 issue of Roadracing World Motorcycle Technology magazine, which is now being printed.

Race-Use-Only Bike Brings Buell Full Circle

EAST TROY, Wis. (January 23, 2006) – Erik Buell and company come full circle with the introduction of the 2007 Buell XBRR, a limited-edition production racing motorcycle designed exclusively for closed course competition. A spiritual successor to Buell-s first motorcycle, the 1983 RW750, the XBRR is poised to change the face of privateer racing with a professional-level, race-ready, production-based platform featuring top-shelf racing technology and typical Buell innovation.

-The XBRR combines the current culmination of Buell-s leading edge chassis technology and Harley-Davidson-s air-cooled V-Twin powertrain development in a platform designed by and developed for dedicated racers,- said Erik Buell, Chairman and Chief Technical Officer, Buell Motorcycle Company.

For Erik Buell, the XBRR marks a return to his racing roots. As a successful privateer road racer early in his career, Buell eventually built his own race bikes for the AMA’s then-premier Formula 1 class. The RW750 was a hand-built race bike, and it became the first official Buell motorcycle.

Two were produced before the AMA discontinued the class after 1985. Buell then translated his race-bred design principles into a line of successful street bikes leading up to the current XB platform.

The Buell XBRR features a modified XB Thunderstorm 1339cc (103.6mm bore x 79.4mm stroke) air/oil-cooled V-Twin motor rated at 150-hp (measured at the crankshaft). The engine is fed by a dual-downdraft 62mm throttle-body electronic fuel injection system and a ram-air intake system integrated with a new wind-tunnel developed carbon fiber fairing.

The XBRR is the first production Buell since the 1988-89 RR1200 to feature a full fairing. Its lightweight carbon design integrates ducts for cooling of the engine and oil cooler. The fairing was extensively wind tunnel tested to improve aerodynamics and reduce drag.

The XBRR chassis is the revolutionary XB design with fuel-in-the-frame and oil-in-the-swingarm, modified with a billet axle adjustment system and chain-drive to allow gearing changes for different race tracks. Suspension travel is managed by fully adjustable Ohlins units, with 43mm front forks and a remote-reservoir rear shock.

A new ZTL2 (Zero Torsional Load) eight-piston front caliper grabs a standard XB front rotor providing outstanding braking performance, but with less weight than conventional designs. New XBRR six-spoke magnesium wheels weigh 33 percent less than standard XB wheels.

Instruments include tachometer, indicator lamps for shift, power on and low oil pressure. The XBRR features a unique Buell Racing paint scheme.
