Rider Profile

Best ForThis is a demanding, light, high-strung machine best suited to intermediate and experienced riders comfortable with an aggressive supermoto stance and abrupt single-cylinder power delivery.
PurposeBuilt for flicking through tight corners and urban streets or attacking a supermoto track day, not for covering long distances or carrying luggage.
Rider FitThe tall 870mm seat height, minimal weight, and firm long-travel suspension favor taller, fitter riders who don't mind an upright, compact riding position.
CharacterA raw, punchy, and playful single-cylinder supermoto that rewards precise, active riding with sharp handling and thrilling agility.
Not Ideal ForThis bike is not for riders seeking plush comfort, passenger-friendly ergonomics, or a relaxed long-distance touring experience.

2003 Husaberg FS 400 C Rider Ergonomics Assessment

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

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2003 Husaberg FS 400 C, with a relaxed knee angle of around 140 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.
