Rider Profile

Best ForThis is a beginner-friendly machine, ideal for new riders building confidence and skill.
PurposeIt's best suited to light urban commuting, learning to ride, and short low-speed jaunts rather than any serious performance riding.
Rider FitIts low seat height and light dry weight make it very easy to handle for riders of smaller stature or limited strength.
CharacterThe single-cylinder retro-naked styling and modest, torque-light power delivery give it a docile, approachable, old-school charm.
Not Ideal ForIt is not suited to highway touring, carrying a passenger any real distance, or riders seeking speed and excitement.

2001 Yamaha SR 125 Rider Ergonomics Assessment

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

Feet:

At 730mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2001 Yamaha SR 125, with a moderate knee angle of around 105 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.
