Rider Profile

Best ForSuitable for riders of any experience level thanks to its automatic belt drive and approachable, scooter-style ergonomics.
PurposeDesigned as a comfortable maxi-scooter for commuting and light touring rather than outright performance.
Rider FitThe low seat height and step-through layout make it easy to manage for shorter or less physically strong riders, though its 212 kg weight requires some care at low speed and when maneuvering.
CharacterA practical, relaxed and easygoing machine that prioritizes comfort, weather protection, and effortless twist-and-go usability over sportiness.
Not Ideal ForNot a good fit for riders seeking sharp handling, high-speed thrills, or any off-road capability.

2004 Yamaha Majesty 400 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 2004 Yamaha Majesty 400, with a moderate knee angle of around 105 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.
