Rider Profile

Best ForBeginner-friendly thanks to its light weight, low power, and forgiving nature, though tall seat height suits riders comfortable with off-road ergonomics.
PurposeBuilt primarily as a lightweight trail and enduro bike for tackling technical off-road terrain rather than covering ground quickly.
Rider FitVery manageable physically due to its low dry weight and slim chassis, though the tall 810mm seat height demands reasonable inseam length.
CharacterA nimble, air-cooled single-cylinder trail bike that rewards playful, momentum-based riding over raw speed or highway cruising.
Not Ideal ForNot suited for riders wanting high-speed highway touring, passenger comfort, or aggressive on-road performance.

2012 Yamaha Serow 250 Rider Ergonomics Assessment

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

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Yamaha Serow 250, 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.
