Rider Profile

Best ForSuitable for newer riders as well as experienced cruiser fans thanks to its low seat height and manageable power delivery.
PurposeBuilt for relaxed boulevard cruising and short-to-medium rides where style and low-end torque matter more than outright speed.
Rider FitThe low 27-inch seat height and cruiser ergonomics make it accessible to shorter riders, though the 610-plus pound wet weight demands confident low-speed handling.
CharacterA classic V-twin custom cruiser with a big front wheel, laid-back stance, and torque-focused feel rather than high-rev excitement.
Not Ideal ForNot a good fit for riders seeking sharp cornering performance, high-speed touring comfort, or any kind of off-road capability.

2020 Kawasaki Vulcan 900 Custom Rider Ergonomics Assessment

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

Feet:

At 685mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Kawasaki Vulcan 900 Custom, 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.
