Rider Profile

Best ForSuitable for riders with basic scooter or automatic-transmission experience, including those stepping up from smaller scooters.
PurposeDesigned primarily as a sporty, high-performance commuter that blends scooter convenience with maxi-scooter power and stability.
Rider FitThe low seat height and automatic transmission make it accessible, though its weight requires a bit more effort at low speeds and when maneuvering it stationary.
CharacterA confident, sporty maxi-scooter that feels planted at speed and rewards spirited riding through corners thanks to its wide tires and firm chassis.
Not Ideal ForNot ideal for off-road exploration or riders seeking a lightweight, easily flickable machine for tight city parking.

2004 Yamaha Tmax 500 Rider Ergonomics Assessment

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

Feet:

At 795mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Yamaha Tmax 500, 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.
