Rider FitIts very light weight and low seat height make it extremely accessible for riders of small stature or limited strength.
CharacterIt has a friendly, unintimidating, and practical personality suited to relaxed, low-effort city riding.
Not Ideal ForThis scooter is not suitable for highway travel, touring, carrying a passenger comfortably, or anyone seeking performance or excitement.

2011 Yamaha Vox Rider Ergonomics Assessment

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

Feet:

At 735mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Yamaha Vox, with a moderate knee angle of around 95 degrees and a slightly forward 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.
