Rider Profile

Best ForThis is an approachable, forgiving machine well suited to beginners and newer riders building confidence.
PurposeDesigned primarily as a lightweight commuter and city naked bike rather than a performance or adventure machine.
Rider FitIts low seat height and light 148 kg weight make it easy to handle for shorter or less physically strong riders.
CharacterA nimble, single-cylinder naked bike that favors agility and everyday usability over outright speed or power.
Not Ideal ForNot a good fit for riders wanting high-speed touring, off-road capability, or two-up long-distance comfort.

2015 Kawasaki Z250SL 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 2015 Kawasaki Z250SL, with a moderate knee angle of around 115 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.
