Rider FitLow 705mm seat height and manageable 226kg weight make it accessible to shorter or less experienced riders.
CharacterA modern, sporty-styled cruiser that trades raw power for smooth, confidence-inspiring handling and easy low-speed manners.
Not Ideal ForNot the right choice for riders seeking high-speed performance, off-road capability, or serious two-up touring comfort.

2021 Kawasaki Vulcan S SE 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 SE, 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.
