Rider Profile

Best ForThis is a friendly, forgiving middleweight naked bike well suited to new and lower-experience riders, including those just off a learner license.
PurposeIt's designed primarily as an approachable everyday commuter and learner-friendly naked bike rather than a performance or adventure machine.
Rider FitA low seat height and modest 199 kg weight make it manageable for shorter or less physically strong riders to handle at a stop and in slow maneuvers.
CharacterThe parallel-twin engine and steel diamond frame give it a mellow, predictable, and easygoing character rather than an aggressive or thrilling one.
Not Ideal ForIt's not the right choice for riders seeking high-speed thrills, serious touring range, or any off-road capability.

2013 Kawasaki ER-4N Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2013 Kawasaki ER-4N, 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.
