Rider Profile

Best ForThis bike suits newer or lighter riders who want a small, manageable machine to build confidence on before moving to bigger motorcycles.
PurposeIt is best suited to short urban hops and light supermotard-style fun rather than serious speed or distance riding.
Rider FitIts low dry weight and modest seat height make it easy to handle and forgiving for smaller or less experienced riders.
CharacterIt has a light, flickable, playful feel typical of small-displacement supermotard-styled bikes rather than raw power or stability.
Not Ideal ForThis is not the right bike for riders wanting highway speed, long-distance touring comfort, or serious off-road capability.

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

2007 Yamaha DT50X 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 2007 Yamaha DT50X, with a relaxed knee angle of around 130 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.
