Rider Profile

Best ForThis is an ideal machine for beginners or learner-permit riders taking their first steps into supermoto-style riding.
PurposeBuilt for light, nimble urban commuting and playful low-speed cornering rather than outright performance.
Rider FitIts very low weight and accessible seat height make it easy to manage for smaller or less experienced riders.
CharacterA small, sprightly single-cylinder machine that rewards flickable handling over raw speed.
Not Ideal ForThis is not the bike for highway touring, carrying a passenger comfortably, or riders seeking strong acceleration.

2009 Yamaha XT125X Rider Ergonomics Assessment

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

Feet:

At 860mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2009 Yamaha XT125X, with a relaxed knee angle of around 130 degrees and a slightly forward 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.
