The Buell XBRR marks a triumphant return to its racing roots, channeling the pioneering spirit of Erik Buell’s earliest creations.
This limited-edition production motorcycle is designed exclusively for closed-course competition, boasting cutting-edge technology and innovative design that embodies the essence of privateer racing. The 1339cc air/oil-cooled V-Twin engine, derived from the XB Thunderstorm platform, unleashes a potent 150-hp at the crankshaft, courtesy of dual-downdraft fuel injection and a ram-air intake system.
The XBRR’s aerodynamic full fairing, crafted with wind-tunnel precision, seamlessly integrates ducts for cooling and features an advanced lightweight carbon design. This production-based platform represents the culmination of Buell’s leading-edge chassis technology and Harley-Davidson’s air-cooled V-Twin powertrain development, expertly blended to deliver a professional-level riding experience.
The Buell XBRR is poised to dominate privateer racing with its unparalleled performance, precision engineering, and attention to detail – an unyielding testament to Erik Buell’s unwavering passion for motorcycle innovation.
