Rider Profile

Best ForBest suited to newer or smaller-statured riders, as well as experienced riders looking for a light, playful city bike.
PurposeDesigned as a sharp-handling supermoto for flicking through city traffic and tight, twisty backroads rather than covering long distances or high speeds.
Rider FitVery light dry weight and a tall but narrow seat make it easy to manage at a stop and toss around at low speed, though the 870mm seat height may challenge shorter riders.
CharacterA nimble, high-revving single-cylinder machine that rewards an eager, playful riding style over outright power or long-distance comfort.
Not Ideal ForNot a good fit for riders wanting sustained high-speed cruising, long motorway touring, or serious off-road capability.

2004 Husqvarna SM 125 S 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 2004 Husqvarna SM 125 S, 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.
