2023 Bimota KB4 RC

2023 Bimota KB4 RC sits at the sharper end of the Rimini firm's Kawasaki-based lineup, pairing the KB4's four-cylinder muscle with a race-focused chassis that leans hard into full-throttle handling. This is a bike built around the Kawasaki inline-four engine dressed in Bimota's own carbon-and-billet frame, which means the character comes less from raw output and more from how precisely the chassis translates rider input at speed. Around town it's demanding and a little impractical, but on a fast, flowing road or a track day, the RC rewards commitment with a level of feedback few mass-produced sportbikes can match. It's a machine that asks you to ride it properly rather than commute on it. The 2023 model carried over without significant mechanical changes from the prior year, buyers comparing it to a 2022 example should focus on mileage, service history, and condition rather than spec differences. Owners tend to be experienced riders trading up from mainstream literbikes, drawn to the exclusivity and hands-on engineering as much as performance. Given Bimota's low production numbers, collector interest here runs high, and clean examples are increasingly treated as investment pieces rather than daily riders.
