42 fields on record
The 2026 Bimota KB4RC shares its 1043cc Kawasaki-derived inline-four (140 HP) and trellis-and-billet chassis with the standard KB4, positioned as the sportier-focused variant in Bimota's KB4 line. It carries the same Brembo brakes, quick-shifter-ready six-speed gearbox and carbon-fibre bodywork as the KB4, aimed at riders who want the naked KB4's engine and handling in a more track-oriented package.
