Rider Profile

Best ForSuits newer to intermediate riders thanks to its manageable midrange power delivery and forgiving parallel-twin character.
PurposeBest suited to everyday commuting and around-town riding with occasional spirited weekend rides on twisty roads.
Rider FitA moderate 805mm seat height and lightweight 204kg chassis make it accessible for riders of average and shorter stature.
CharacterAn approachable, torquey naked twin that feels lively in town without being intimidating.
Not Ideal ForNot ideal for dedicated long-distance touring or serious off-road use given its street-focused suspension and limited wind protection.

2006 Kawasaki ER-6N 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 2006 Kawasaki ER-6N, 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.
