Rider Profile

Best ForWell suited to beginners or casual riders due to its low power output and light, manageable chassis.
PurposeDesigned as a quirky, low-speed fun bike for light trail exploration and easy urban runabout duties rather than serious performance.
Rider FitIts low seat height, light dry weight, and narrow single-cylinder power delivery make it very approachable for shorter or less experienced riders.
CharacterA distinctive, playful little machine known for its oversized balloon tires and go-anywhere charm rather than outright capability.
Not Ideal ForNot suited for highway travel, long-distance touring, or riders seeking real off-road performance or two-up comfort.

2001 Yamaha TW 125 Rider Ergonomics Assessment

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

Feet:

At 815mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2001 Yamaha TW 125, with a relaxed knee angle of around 120 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.
