Rider Profile

Best ForThis is a learner-legal moped-class enduro, best suited to beginners, young riders, or those restricted to very small displacement machines.
PurposeDesigned as a lightweight play-bike for light trail riding, moped-class commuting, and learning off-road basics rather than any kind of speed or distance work.
Rider FitIts tall 900mm seat height and dirt-bike stance suit riders comfortable standing on pegs, but its featherweight build makes it manageable for smaller or lighter riders too.
CharacterA nimble, high-revving two-stroke that rewards momentum-carrying and playful riding over raw power.
Not Ideal ForThis is not the bike for highway travel, carrying a passenger, or anyone wanting real acceleration or long-distance comfort.

2008 Yamaha DT50R Rider Ergonomics Assessment

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

Feet:

At 900mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2008 Yamaha DT50R, with a cramped knee angle of around 80 degrees and an upright riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
