Rider Profile

Best ForWell suited to beginner and intermediate riders thanks to its light weight, modest power, and forgiving 2-stroke single character.
PurposeBuilt primarily for trail riding, green-laning, and light off-road exploration rather than outright speed or long-distance travel.
Rider FitTall seat height and slim, lightweight chassis suit riders who can comfortably handle a dirt-bike-style stance and don't need low-seat accessibility.
CharacterA nimble, playful enduro-styled machine that rewards momentum-carrying, flickable riding over raw horsepower.
Not Ideal ForNot a good match for riders wanting highway comfort, passenger carrying, or high-speed touring capability.

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

Feet:

At 915mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2007 Yamaha DT 125 RE, 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.
