Rider Profile

Best ForBest suited to riders with prior experience on powerful, heavy naked bikes given the strong torque and substantial mass.
PurposeA retro-styled muscle naked built for punchy straight-line performance and old-school Superbike-inspired street presence rather than outright track precision.
Rider FitThe 800mm seat height and 221kg dry weight make it manageable for average-height riders but demand reasonable strength at low speed and when maneuvering.
CharacterDelivers a raw, torque-heavy in-line four experience with classic 1990s-2000s muscle bike charisma and analog rider feedback.
Not Ideal ForNot ideal for beginners, off-road use, or riders seeking a lightweight, flickable machine for tight technical corners.

1999 Kawasaki ZRX 1100 Rider Ergonomics Assessment

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 1999 Kawasaki ZRX 1100, 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.
