The 2007 Buell XB RR motorcycle was made in the United States. It featured an air-cooled, vee-twin four stroke engine. The ignition is by C.D.I. The engine was rated at 150 crankshaft bhp @ 8,000 rpm. The engine displacement was 1339cc based upon a bore and stroke of 104 X 79.4mm. Fuel was supplied via a injection by twin 62mm throttle bodies. Getting the power to the ground was by a five speed transmission. The suspension featured front Ohlins 43mm inverted telescopic forks and a rear Ohlins single shock. Braking was accomplished by front and rear single disc. The motorcycle weighed in at 362 pounds. Top speed for the bike is not available. Production was limited to 50 motorcycles.

According to the museum's fact sheet "The XB RR was built to compete in the American Motorcyclist Assn. Formula Extreme class, where an air cooled push rod twin with a capacity not exceeding 1340cc can compete iwth 600cc four cylinder bikes. While the chassis was state of the art, and the fairing was designed in a wind tunnel, the motorcycle was not competitive and the programme was discontinued."
