Rider Profile

Best ForThis bike suits an intermediate to experienced rider who is comfortable with a heavy, torquey retro-styled naked machine.
PurposeIt's built for riders who want big-bore muscle-bike thrills with a retro Kawasaki styling twist, equally happy blasting backroads or cruising boulevards.
Rider FitAt 228 kg dry with a 790 mm seat height, it demands a rider of reasonable height and strength, especially at low speed or when maneuvering.
CharacterIt has a big-hearted, muscular in-line four character with strong midrange torque, a firm chassis, and old-school street-fighter attitude rather than razor-sharp modern agility.
Not Ideal ForIt's not a good fit for brand-new riders, or anyone wanting a lightweight commuter or a genuine off-road capable machine.

Rider Fit Visualizer

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

Feet:

At 790mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2003 Kawasaki ZRX 1200 S, 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.
