Rider Profile

Best ForBest suited to intermediate or experienced riders who appreciate a torquey, characterful V-twin with sharp handling.
PurposeBuilt as a sporty naked streetfighter designed for aggressive backroad carving and lively urban riding rather than outright top-speed pursuits.
Rider FitThe low seat height and compact, mass-centralized chassis make it approachable, though the firm sporty ergonomics favor an active riding style over long stints.
CharacterDelivers a raw, torque-rich Harley-derived V-twin growl combined with genuinely sharp, flickable handling thanks to its low weight and steep rake.
Not Ideal ForNot the right choice for riders wanting plush long-distance comfort, pillion-friendly touring, or any serious off-road capability.

Rider Fit Visualizer

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

Feet:

At 777mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2006 Buell Lightning CityX XB9SX, with a moderate knee angle of around 115 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.
