Best ForBest suited to intermediate or experienced off-road riders comfortable with a tall, lightweight, aggressive enduro machine.
PurposeBuilt as a competition-focused enduro machine for trails, cross-country events, and technical off-road riding rather than road use.
Rider FitThe tall 870mm seat height and minimal weight favor taller, fit riders who can stand and maneuver the bike actively.
CharacterA sharp, race-bred dirt tool with premium suspension and brakes that rewards an aggressive, standing-up riding style.
Not Ideal ForNot a good fit for riders wanting a comfortable commuter, a passenger-friendly bike, or sustained highway touring.

2013 Rieju Marathon 125 Pro Competizione 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 Competizione, with a cramped knee angle of around 75 degrees and an upright 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.
