Rider Profile

Best ForBest suited to intermediate or experienced riders who appreciate a torquey, characterful V-twin with a firm, sporty edge.
PurposeBuilt for sport-touring riders who want to cover distance while still enjoying twisty roads along the way.
Rider FitThe 800mm seat height and moderate weight make it manageable for most rider sizes, though the firm suspension and sporty ergonomics reward a fit, engaged riding posture.
CharacterA gritty, torque-rich American V-twin with a distinctive exhaust growl and a taut chassis that favors direct, muscular handling over plush refinement.
Not Ideal ForNot a good fit for riders seeking plush long-haul comfort, off-road capability, or a beginner-friendly, low-effort ride.

1999 Buell S3T Thunderbolt 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 1999 Buell S3T Thunderbolt, with a relaxed knee angle of around 120 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.
