The Bimota KB4RC is proof the company never does anything boring—part cafe racer art, part engineering flex, and entirely lust-worthy.
The Bimota machine is a cocktail of Italian craftsmanship and Japanese muscle, blending a hand-assembled chassis with Kawasaki’s snarling 1,043cc inline-four. That’s 140 horses wrapped in a lightweight frame, tuned not just for speed but for sheer riding pleasure.
Bimota KB4RC Is a Machine I Want
If the standard KB4 was a refined espresso, the RC is a double shot with an extra kick.
Adjustable ergonomics mean it molds to the rider like a tailor-made suit, while the pièce de résistance—a three-piece aluminum swingarm—looks like it rode straight off a MotoGP grid. That swingarm, along with Öhlins suspension and Brembo brakes, ensures this machine is more than just a pretty face.

Bimota’s signature chrome-moly trellis frame is bolted to the engine, keeping weight down and balance perfect. Cooling is handled by an under-seat radiator, keeping things tight and tidy.
All this exotic hardware comes at a price—4,730,000 yen ($31,798 USD). When it drops on March 25th, will you be ready to justify the expense? If you’ve got the cash and the craving, the KB4RC is waiting.
