Rider Profile

Best ForSuitable for riders with some scooter or automatic-transmission experience who want a bigger, more substantial machine than a typical city scooter.
PurposeDesigned as a maxi-scooter for comfortable commuting and light touring, blending car-like convenience with motorcycle-style presence.
Rider FitIts low seat height and automatic transmission make it accessible, though its considerable weight requires care at low speed and when maneuvering.
CharacterA relaxed, practical, and comfort-oriented machine that prioritizes smooth power delivery and stability over outright performance.
Not Ideal ForNot for riders seeking sharp handling, off-road capability, or high-speed thrills.

2011 Honda SW-T400 Rider Ergonomics Assessment

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

Feet:

At 740mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Honda SW-T400, 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.
