Bimota Kb4

The Bimota Kb4 has a top speed of ~240 km/h (estimated), produces 140 hp and weighs 189 kg. Motoryk rates it 7.5/10.

Der Bimota KB4 wurde 2023 eingeführt und bedeutete für den italienischen Boutique-Hersteller eine wegweisende Rückkehr zu Maschinen mit Kawasaki-Antrieb, nachdem Kawasaki 2019 eine 49-prozentige Beteiligung an Bimota übernommen hatte. Der KB4 wurde rund um den Kawasaki Z1000 Reihenviermotor gebaut und belebte die KB-Namenslinie, die bis zum legendären KB1 von 1978 zurückreicht, wieder auf. Er zeichnet sich durch die Kombination der handgefertigten italienischen Fahrwerkskunst von Bimota mit dem bewährten Triebwerk von Kawasaki aus und bietet so eine exklusive und leichte Alternative zu in Serie hergestellten Supernakeds.

Was Käufer wissen sollten

⚙️

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.

Wealthy enthusiasts wanting Italian exotic, Japanese reliability

"An exotic gamble that rewards obsessive buyers with deep pockets."

$18,000-$28,000 used

The KB4 is essentially a Kawasaki Z1000-engined exotic wearing bespoke Italian bodywork, and that's both its greatest strength and its most important caveat. You're getting that punchy 1043cc inline-four wrapped in Bimota's trademark trellis frame and hand-built aluminum bodywork — genuinely special stuff that turns heads like almost nothing else on the road. Ownership costs reflect that exclusivity brutally, so budget accordingly before you fall in love with the photos. Used examples are rare enough that condition varies wildly. Check the frame welds carefully — Bimota's small-batch production means quality control isn't Toyota-level. The Kawasaki drivetrain is bulletproof and parts are cheap, but anything Bimota-specific becomes an expensive phone call to specialists. Avoid bikes without full service history; previous owners who skimped on maintenance are a red flag on a machine this exotic. Electronics are relatively simple by modern standards, which is actually a blessing.
