Rider Profile

Best ForThis is a hyper-sport flagship best suited to experienced riders comfortable with big, fast in-line fours and aggressive power delivery.
PurposeBuilt primarily as a high-speed sport and hypersport machine for open roads and track days rather than commuting or exploring.
Rider FitThe 820 mm seat height, sporty ergonomics, and 210 kg dry weight demand a fit, reasonably tall rider comfortable with committed riding posture.
CharacterA brutally fast, big-bore in-line four with a stiff aluminum monocoque frame and premium adjustable suspension, delivering top-tier straight-line performance and confident high-speed stability.
Not Ideal ForNot a good fit for new riders, those wanting an upright relaxed commuter, or anyone seeking off-road capability or long-distance touring comfort.

Rider Fit Visualizer

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

Feet:

At 818mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2004 Kawasaki Ninja ZX-12R, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
