Bimota Kb4
The Bimota KB4 was introduced in 2023, representing a landmark return to Kawasaki-powered machines for the Italian boutique manufacturer following Kawasaki's acquisition of a 49% stake in Bimota in 2019. Built around the Kawasaki Z1000 inline-four engine, the KB4 revived the KB naming lineage that dates back to the legendary KB1 of 1978. It is notable for combining Bimota's handcrafted Italian chassis artistry with Kawasaki's proven powerplant, offering an exclusive and lightweight alternative to mass-produced supernakeds.

What Buyers Should Know
Kawasaki Heart, Bimota Soul
The KB4 uses Kawasaki's proven 1043cc inline-four engine from the Z1000, giving buyers access to a well-documented, reliable powerplant with widely available parts and service knowledge.
Extreme Rarity Holds Value
With very limited production numbers, the KB4 commands strong resale value and is unlikely to depreciate sharply — making it as much a collectible as a rider.
Specialist Servicing Required
Bimota's unique trellis frame and hub-center steering system require specialist knowledge to service correctly, so buyers should budget for experienced technicians and factor in limited local workshop availability.
