2026 Bimota KB 399

With the all-new KB 399, Bimota is bringing a 400 back to market for the first time in decades — and in its usual exclusive manner. The technical base is the Kawasaki Ninja ZX-4RR, whose 399 cc inline-four produces 77 hp in KB tuning at 14,500 rpm and revs up to 16,000 rpm. The standard model features a fully adjustable Showa SFF-BP fork (41 mm) and Brembo Stylema front calipers. A custom Akrapovič titanium exhaust and CNC-machined triple clamps underline the Bimota identity. The Edizione Speciale adds carbon bodywork and an Öhlins STX46 rear shock.

Anyone looking for a calm, everyday motorcycle will not find it here: the KB 399 is clearly focused on sportiness, and pricing will likely sit well above the Kawasaki Ninja ZX-4RR. Deliveries in Europe are planned during 2026. The target group consists of passionate sport riders looking for the Bimota experience in a compact format.

The most natural competitor is the Kawasaki Ninja ZX-4RR, which offers identical mechanics at a fraction of the price.
