Rider Profile

Best ForSuited to new-to-intermediate riders thanks to its light weight, low power, and forgiving handling.
PurposeBuilt as a nimble, street-biased supermoto for flicking through city traffic and carving tight, twisty backroads rather than covering long distances or going off-road.
Rider FitIts low 115kg dry weight and narrow supermoto ergonomics make it easy to manage for smaller or less physically strong riders, though the 870mm seat height demands reasonable inseam length.
CharacterA playful, flickable little street hooligan that rewards aggressive cornering lines and quick direction changes over outright speed.
Not Ideal ForNot a good fit for riders wanting highway touring comfort, serious off-road capability, or strong outright acceleration.

2013 Rieju Marathon 125 Pro SM 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 2013 Rieju Marathon 125 Pro SM, 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.
