Rider Profile

Best ForWell suited to newer riders or those on a restricted license who want a light, playful supermoto to build skills on.
PurposeDesigned for flickable urban riding and sharpened cornering fun rather than outright speed or distance covering.
Rider FitIts tall seat height and slim, light chassis make it easy to manage for most body sizes despite the lofty stance.
CharacterA nimble, high-revving small-bore supermoto that rewards an energetic, momentum-focused riding style.
Not Ideal ForNot a good match for riders wanting sustained highway speeds, long-distance touring comfort, or serious off-road capability.

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 2022 Rieju Marathon 125 SM Pro, with a relaxed knee angle of around 135 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.
