BUELL INTRODUCES XBRR PRODUCTION RACING MOTORCYCLE

Race-use-only bike brings Buell full circle

EAST TROY, Wis. -- (Monday, 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.
