Rider Profile

Best ForBest suited to riders who already have basic motorcycle skills and want to learn genuine off-road technique, since the tall seat, light weight, and peaky two-stroke power reward confidence over brute experience.
PurposeBuilt as a lightweight, nimble enduro for trail riding, green lanes, and playful off-road exploration rather than outright speed or long-distance travel.
Rider FitIts low dry weight and slim chassis make it easy to muscle around at low speed and pick up if dropped, though the 885mm seat height demands reasonable inseam length or confident tiptoe balance.
CharacterA buzzy, high-strung two-stroke single that feels most alive when revved hard, delivering an eager, flickable, go-kart-like personality rather than sustained highway pull.
Not Ideal ForNot a good match for riders wanting a comfortable long-distance tourer, a passenger-friendly bike, or strong stability and outright speed on paved roads.

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

Feet:

At 890mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2001 Yamaha DT 125 R, with a cramped knee angle of around 80 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.
