Rider Profile

Best ForIdeal for beginners or anyone wanting a simple, low-stress twist-and-go ride with no gear shifting to worry about.
PurposeBuilt purely as a lightweight commuter scooter for short urban trips, errands, and weaving through traffic.
Rider FitVery light and low seat height make it easy to handle for riders of nearly any size or experience level, including smaller or shorter riders.
CharacterA practical, no-nonsense city runabout that prioritizes fuel efficiency and manageability over performance or excitement.
Not Ideal ForNot suitable for highway speeds, long-distance touring, off-road use, or riders seeking any real performance or power.

2023 Yamaha Mio Gear 125 Rider Ergonomics Assessment

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

Feet:

At 750mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2023 Yamaha Mio Gear 125, with a moderate knee angle of around 95 degrees and a slightly forward 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.
