Rider Profile

Best ForThis bike suits experienced riders who are confident with high-revving, powerful sportbikes and aggressive geometry.
PurposeBuilt for spirited canyon carving and track-day performance, prioritizing razor-sharp handling over practicality.
Rider FitThe committed sport riding position and high seat height demand good flexibility and place significant weight on the wrists and shoulders during slow-speed riding.
CharacterA boutique Italian exotic with a Kawasaki-derived inline-four heart, blending exclusive craftsmanship with serious performance credentials.
Not Ideal ForThis is not the right bike for new riders, commuters seeking comfort, or anyone planning long-distance touring or two-up travel.

Rider Fit Visualizer

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

Feet:

At 810mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2023 Bimota KB4RC, 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.
