Rider Profile

Best ForThis bike suits newer or smaller riders and those wanting a light, unintimidating machine to build off-road skills, though its tall seat height demands reasonable inseam confidence.
PurposeIt is built primarily for trail riding, technical enduro tracks, and low-speed off-road exploration rather than any kind of speed or highway work.
Rider FitThe very low dry weight and slim chassis make it easy to muscle around, lift, and paddle through tricky terrain, but the tall seat height can challenge shorter riders.
CharacterIt has the character of a nimble, willing little enduro trail bike, eager to be flicked around obstacles but with only modest engine punch.
Not Ideal ForIt is not suited to riders wanting sustained highway speeds, long-distance touring comfort, or carrying a passenger any real distance.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.

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

Feet:

At 890mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2018 Rieju Marathon 125 Pro, with a cramped knee angle of around 80 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.
