Rider Profile

Best For	Ideal for beginners and returning riders; forgiving power delivery and light weight also make it a fun commuter or track-day starter for experienced riders.
Purpose	A lightweight sport bike for spirited canyon rides, commuting, and entry-level track days rather than long-distance touring.
Rider Fit	Compact and light at 164kg dry with a manageable 785mm seat; sporty but not extreme riding posture with mild forward lean and small windscreen.
Character	Nimble, approachable, and revvy parallel-twin sportbike that punches above its 399cc for grins without intimidating newer riders.
Not Ideal For	Not for riders wanting big-bore highway punch, two-up touring range (tiny 3.7L tank), or any off-road use.

Inseam (optional)

Units

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 2020 Kawasaki Ninja 400, with a cramped knee angle of around 70 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.
