Rider Profile

Best ForThis is a beginner-friendly machine, ideal for young riders or newcomers learning off-road basics.
PurposeBuilt as a light trail and recreational off-road bike for casual dirt riding rather than speed or long distances.
Rider FitIts low seat height and very light wet weight make it easy to manage for smaller or less experienced riders.
CharacterA simple, forgiving, low-stress little trail bike that rewards smooth, easygoing riding over aggression.
Not Ideal ForNot suitable for highway travel, two-up touring, or riders seeking strong power and high-speed performance.

Rider Fit Visualizer

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

Feet:

At 775mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2019 Yamaha TT-R125, with a cramped knee angle of around 65 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.
