Rider Profile

Best ForSuitable for riders with a full motorcycle license or scooter endorsement who want automatic convenience without prior manual-shifting experience.
PurposeBuilt primarily as a commuter and urban mobility scooter that can also handle occasional weekend rides beyond the city.
Rider FitThe 785mm seat height and 215kg weight are manageable for average-height riders, though the bulk requires some care at low speed and when parking.
CharacterA practical, comfort-oriented maxi-scooter that prioritizes smooth automatic power delivery, wind protection, and storage over outright sportiness.
Not Ideal ForNot suited for off-road use, track riding, or riders seeking an engaging manual gearbox and aggressive sport handling.

2016 Yamaha X-MAX 400 Rider Ergonomics Assessment

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

Feet:

At 785mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2016 Yamaha X-MAX 400, with a moderate knee angle of around 110 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.
