Rider Profile

Best ForThis bike suits an intermediate to experienced rider who enjoys a quirky, characterful machine that rewards confident, aggressive inputs.
PurposeBuilt primarily as a light, sharp-handling sport streetfighter for tight, twisty roads rather than outright top speed or long-distance touring.
Rider FitIts low dry weight and compact, mass-centralized chassis make it easy to muscle around, though the short wheelbase and firm suspension demand an active riding style.
CharacterDistinctive V-twin torque delivery, aggressive geometry, and unconventional engineering give it a raw, mechanical personality unlike typical Japanese sportbikes.
Not Ideal ForNot a good fit for riders wanting plush comfort, pillion-friendly ergonomics, or a machine suited to relaxed long-haul touring.

2003 Buell Firebolt XB9R Rider Ergonomics Assessment

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

Feet:

At 775mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2003 Buell Firebolt XB9R, with a cramped knee angle of around 65 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.
