Rider Profile

Best ForThis bike suits beginners and experienced riders alike who want a light, forgiving machine to build confidence on varied terrain.
PurposeIt's best suited to commuting, trail exploration, and general dual-sport fun rather than outright speed or long-distance touring.
Rider FitThe tall seat height and slim, lightweight chassis favor riders of average to taller stature who want easy maneuverability over sheer power.
CharacterIt has the personality of a nimble, playful trail companion, happiest picking through tight streets or unpaved paths rather than chasing top speed.
Not Ideal ForIt's not for riders seeking high-speed highway cruising, heavy touring capability, or carrying a passenger in comfort.

2013 Yamaha WR125R 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 2013 Yamaha WR125R, with a cramped knee angle of around 75 degrees and an upright 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.
