Rider Profile

Best ForWell suited to newer and intermediate riders thanks to its modest power delivery and manageable weight.
PurposeDesigned primarily as an agile, fun urban and B-road naked bike rather than a high-speed or long-distance machine.
Rider FitA low seat height and light overall weight make it accessible for shorter or less experienced riders to handle confidently.
CharacterThe V-twin engine gives a torquey, characterful feel with smooth low-to-mid range pull rather than outright top-end thrills.
Not Ideal ForNot the right choice for riders wanting serious touring range, passenger comfort, or off-road capability.

2011 Suzuki Gladius 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 2011 Suzuki Gladius 400, with a relaxed knee angle of around 120 degrees and a forward-leaning 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.
