Buell introduced this model for the 2008 model year as a clean-sheet sportbike that marked a major departure from the company’s earlier air-cooled Lightning and Ulysses-era machines. It was the first Buell built around the liquid-cooled Helicon V-twin developed with Rotax, and it represented the brand’s most direct attempt to compete in the liter-class supersport conversation while still preserving Buell’s unconventional engineering approach. Rather than treating it as a conventional inline-four rival, the company packaged the engine in a distinctive chassis that kept the fuel-in-frame concept and the brand’s signature emphasis on centralized mass and sharp handling.
The model arrived during a pivotal moment for Buell. It was launched as the company celebrated a quarter-century of production, and it signaled an effort to open a new chapter beyond the Harley-Davidson-based platform family that had defined Buell up to that point. For enthusiasts, it became especially notable because it was the first and most visible expression of Buell’s new liquid-cooled superbike direction. In 2009, the related café-racer styled 1125CR joined the lineup, but the original fully faired sportbike remained the core of the nameplate.
Production was brief. Buell’s corporate future changed dramatically in 2009 when the brand was divested from Harley-Davidson, and the company’s 1125-era development path was cut short. As a result, this nameplate is remembered as a one-generation, short-run machine from the final period of the original Buell company. Its significance lies less in longevity than in what it represented: a bold, technically ambitious attempt to reimagine the American sportbike using a modern liquid-cooled V-twin and a distinctly Buell chassis philosophy.
