Rider Profile

Best ForThis is an approachable, low-power machine well suited to beginners or riders wanting a light, unintimidating bike for learning throttle and clutch control.
PurposeIt's designed as a small-displacement supermoto-styled commuter for weaving through urban traffic and tackling light mixed-surface streets rather than serious speed or off-road work.
Rider FitThe tall-ish 830mm seat height combined with a very light dry weight of 106kg makes it easy to manage for most body sizes despite the perch.
CharacterIt has a playful, flickable character with supermoto-style 17 inch wheels and street tires that reward nimble handling over outright power.
Not Ideal ForIt's not a good fit for highway touring, carrying a passenger long distances, or riders seeking strong acceleration or high top speed.

2006 Yamaha XT 125 X Rider Ergonomics Assessment

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

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2006 Yamaha XT 125 X, with a relaxed knee angle of around 125 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.
