Rider Profile

Best ForThis lightweight, low-powered single is an excellent choice for beginners or younger riders building confidence off-road and in town.
PurposeDesigned as a small-capacity enduro-styled learner bike, it suits light trail exploration, commuting, and general low-speed fun rather than performance riding.
Rider FitIts very low 120 kg weight and 860 mm seat height make it easy to manage for shorter or less experienced riders.
CharacterIt has a friendly, approachable, non-intimidating character with modest power delivery and simple, forgiving handling.
Not Ideal ForIt is not suited to riders wanting highway speeds, long-distance touring comfort, or serious two-up passenger use.

2008 Yamaha XT125R 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 2008 Yamaha XT125R, with a relaxed knee angle of around 130 degrees and a slightly forward 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.
