Rider Profile

Best ForBest suited to intermediate or experienced off-road riders comfortable with a tall, light, aggressive enduro machine.
PurposeBuilt purely for serious trail riding, enduro competition, and technical off-road terrain rather than road use.
Rider FitThe tall 900mm seat height and lightweight but top-heavy standing riding position demand good fitness, leg length, and off-road riding skill.
CharacterA raw, purposeful dirt bike with premium suspension components that rewards an active, skilled rider who enjoys tackling rough trails.
Not Ideal ForNot a good fit for riders wanting a comfortable daily commuter, a highway tourer, or a passenger-friendly machine.

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

Feet:

At 900mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2011 Rieju Marathon 450, 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.
