Rider Profile

Best ForThis bike suits riders who are new to intermediate in off-road riding, as its light weight and simple single-cylinder design make it forgiving to learn on.
PurposeIt is built primarily for trail riding and light enduro use rather than speed, comfort, or long-distance travel.
Rider FitThe tall 940mm seat height and dirt-bike ergonomics favor riders of average to above-average height and reasonable fitness for standing and maneuvering the bike.
CharacterIt has the character of a nimble, no-frills dirt machine, valuing lightness and maneuverability over refinement or outright power.
Not Ideal ForThis is not the right bike for riders wanting highway speed, passenger comfort, or long paved touring capability.

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

Feet:

At 940mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2008 Orion AGB-31, with a cramped knee angle of around 85 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.
