Rider Profile

Best ForThis is an entry-level trail bike best suited to beginners, younger riders, or those stepping up from a smaller pit bike into their first real off-road machine.
PurposeIt's built for low-speed trail riding, backcountry exploration at a gentle pace, and learning off-road fundamentals rather than any kind of speed or highway use.
Rider FitThe low 31.7-inch seat height and light 198-lb wet weight make it very approachable for smaller or less experienced riders to handle and pick up.
CharacterIt has a friendly, forgiving, and predictable character with mild carbureted power delivery that rewards smooth throttle inputs over aggression.
Not Ideal ForThis bike is not for experienced off-road riders seeking real performance, nor for anyone wanting to ride on highways or cover long touring distances.

2015 Yamaha TT-R125LE Rider Ergonomics Assessment

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

Feet:

At 805mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2015 Yamaha TT-R125LE, with a cramped knee angle of around 70 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.
