1250sc SuperBike


The Roehr 1250sc is the fastest and most powerful American made production sport bike. The specially developed supercharged version of the HD* Revolution* engine provides 180hp.  This power, combined with an innovative Bi-metal composite beam frame, top quality cycle parts and sleek european styling, results in a motorcycle that redefines the American performance bike.  Handcrafted, exclusive, fast and beautiful, a true American thoroughbred


The eRoehr Series feature a unique Bi-Metal beam frame. The frame is constructed of 4130 Chrome-Moly steel and 6061 T6 Aluminum. This method allows each material to be used in areas of the frame that their material characteristics are best suited.  A motorcycle frame needs to be strong, stiff and light weight, but also needs to flex just enough under certain conditions. This controlled flex provides essential information, providing the rider with added confidence near the limits of tire grip. Additionally, this flex also adds a level of dampening which is especially beneficial when the motorcycle is leaned over on the edges of the tires. Under these conditions the motorcycle’s suspension effectiveness is dramatically reduced due to road forces no longer acting on the suspension at parallel angles.

The Roehr Bi-metal frame provides a level of dampening that allows the tire to better follow road irregularities under these conditions.  Through the use of computer assisted finite element analysis, the Bi-metal frame was designed using large section, thin wall, 4130 steel, main chassis beams to provide a stiff yet soft structure that is bonded and bolted to extremely strong, stiff yet light weight billet aluminum swing arm pivot plates.  By combining these materials into one structure, the Roehr Bi-Metal frame provides the ultimate combination of strength, stiffness, controlled flex and light weight. This unique frame technology is a major contributor to the stellar handling characteristics of the eRoehr series.
