Roehr 1250sc supercharged superbike and later 125/250 single-cylinder models
Company History
Roehr Motorcycles pursued American superbike performance through a distinctive path: forced induction. The 1250sc used a supercharged V-twin housed in a purpose-built chassis with premium suspension and braking, targeting European-level speed with American thunder. Development demanded careful thermal management, fueling strategy under boost, and chassis stiffness that preserved feedback at serious pace. Later, the company pivoted to more accessible 125/250 singles to address regulatory and market realities, but the 1250sc remains the conversation piece—an audacious attempt to make a homegrown missile that still felt civilized on a back road. Boutique economics, certification costs, and the Great Recession ultimately stunted volume, yet Roehr’s work proved that small U.S. firms could deliver engineering ambition with polish. Historically, the brand joins Britten and Motus in the canon of American dreamers who tried to bend physics and business to a singular idea: a superbike that speaks with a distinctly American accent.
