Rider Profile

Best ForWell suited to newer and returning riders thanks to its low seat height, manageable weight, and approachable mid-size twin.
PurposeBuilt as an entry-level cruiser-tourer for relaxed road trips and comfortable daily commuting rather than outright performance.
Rider FitThe low 705mm seat height and modest 229kg wet weight make it easy to handle for shorter or less experienced riders.
CharacterA laid-back, torque-friendly cruiser with a sporty-for-its-class chassis that adds a bit of agility to the classic Vulcan feel.
Not Ideal ForNot a good fit for riders wanting high-speed performance, serious off-road capability, or a heavyweight full-dress touring rig.

2021 Kawasaki Vulcan S Tourer Rider Ergonomics Assessment

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

Feet:

At 705mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 Kawasaki Vulcan S Tourer, with a cramped knee angle of around 75 degrees and an upright 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.
