PurposeBuilt for aggressive sport riding and track days, blending forced-induction V-twin power with premium Ohlins and Brembo componentry.
Rider FitThe low clip-ons, high footpegs, and firm sportbike ergonomics favor a fit rider comfortable with an aggressive forward-leaning posture.
CharacterA rare, boutique American superbike with a snarling supercharged 60-degree V-twin that rewards precise, committed riding.
Not Ideal ForThis is not the right bike for beginners, commuters seeking comfort, or anyone wanting a relaxed touring or passenger-friendly ride.

2011 Roehr 1250SC Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Roehr 1250SC, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
