Rider Profile

Best ForNote: this is an off-road sport ATV/quad, not a motorcycle, so the profile is adapted accordingly for riders with at least basic ATV or dirt bike handling experience.
PurposeBuilt for aggressive sport quad riding on trails, dunes, and motocross-style tracks rather than any form of road use.
Rider FitA light, compact single-cylinder sport quad that rewards active body positioning and is manageable for riders of average fitness and strength.
CharacterA nimble, high-revving air-cooled sport ATV with fully adjustable suspension tuned for playful, aggressive off-road handling.
Not Ideal ForNot suitable for anyone wanting street legality, highway touring comfort, or a passenger-friendly two-up machine.

2009 Honda TRX400X Rider Ergonomics Assessment

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

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Honda TRX400X, with a cramped knee angle of around 70 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.
