Rider Profile

Best ForThis is a beginner-friendly bike, ideal for new riders or those wanting a light, unintimidating machine to build confidence on.
PurposeDesigned as a small-capacity trail and learner enduro, best suited to light off-road trails, green lanes, and short urban hops rather than serious speed or distance.
Rider FitIts low dry weight and tall but narrow seat make it manageable for smaller or less experienced riders, though the 860mm seat height may still challenge shorter riders.
CharacterA friendly, nimble, low-stress companion that rewards playful, low-speed maneuvering over outright performance.
Not Ideal ForThis is not the bike for highway touring, carrying a passenger long distances, or riders seeking strong acceleration and top-end power.

2006 Yamaha XT 125 R 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 2006 Yamaha XT 125 R, 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.
