Rider Profile

Best ForThis bike suits an intermediate to experienced rider who enjoys a quirky, torque-heavy V-twin with sharp handling manners.
PurposeBuilt as a light, punchy urban naked with genuine backroad-carving ability thanks to its steep rake and short wheelbase.
Rider FitThe low seat height and light dry weight make it accessible, though the firm sporty ergonomics and short suspension travel favor a fit rider over long stints.
CharacterIt has a distinctive, characterful personality with strong low-end torque, a single-sided front brake rotor, and an unmistakable Buell exhaust note.
Not Ideal ForIt is not a good fit for riders seeking long-distance touring comfort, pillion-friendly space, or any off-road capability.

2010 Buell XB12SX Lightning City X Rider Ergonomics Assessment

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

Feet:

At 726mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Buell XB12SX Lightning City X, with a moderate knee angle of around 105 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.
