“Kb4 & Kb4RC, they both look sleek and fast — just like the process that created it,” said Enrico Borghesan, designer of Bimota. “It went from first sketch to full-size model in few months using computer-aided design — and without missing any of the passion that has made so many Bimota products fun to ride and show off. You ride some bikes because you have to, but you ride these Bimota because you want to.”

2026 Bimota KB4RC: RACING FREEDOM
Introducing the 2026 Bimota KB4RC…
Innovation and performance without compromise!
The KB4RC bimota is unique, with an innovative aesthetic never seen before. The design is instantly recognizable as bimota and “KB4RC”.
As announced, the Bimota Kb4, first shown as a concept bike at the last Eicma in Milan, is now on the production line. Together with it Bimota announce the addition of a new model based on the Kb4 project, the “Vintage-Inspired” Kb4-RC (RaceCafe’)
“No other manufacturer has a motorcycle like Kb4 and Kb4RC,” said Pierluigi Marconi, Bimota General Manager. “No one has this much fun and function in one package.
The Kb4 & Kb4RC are an attention grabber that will act like a halo for Bimota by attracting further consumer attention to our impressive vehicle lineup”.
Marconi noted that Kb4 is the second major product announcement from Bimota in the past 20 months – both breakthrough vehicles that combine Bimota’s heritage with modern day function and flair. Kb4RC is now completing the Bimota model range for 2022.
Earlier in November 2019 Bimota announced TesiH2 to create a kind of vehicle that’s never been seen before.
TesiH2 is part sport-exclusive and part hyper-sport motorcycle, and can be identified to be the latest evolution of innovative Motorcycle chassis design that began in 1982.
TesiH2 is actually on display in Bimota’s shop-in-shop since September 2020.
The production Bimota Kb4 & Kb4RC “Vintage Inspired” will be unique by combining the classic design, of the iconic Bimota motorcycles of the 70’s with the function and utility of a modern bike. In the spirit of Bimota, Kb4 & Kb4RC will be contemporary thoroughbreds – 142hp in-line 4-powered, best handling street machine with an innovative high pressure cooling system. The one-piece radiator is neatly stowed, diagonally between the seat and the rear wheel.
“Kb4 & Kb4RC, they both look sleek and fast — just like the process that created it,” said Enrico Borghesan, designer of Bimota. “It went from first sketch to full-size model in few months using computer-aided design — and without missing any of the passion that has made so many Bimota products fun to ride and show off. You ride some bikes because you have to, but you ride these Bimota because you want to.”
The strong fairing forms are part of Bimota’s rich heritage, but are executed in a very contemporary way.
Other Kb4 exterior design features include the full-width windscreen and prominent Bimota logo that currently appear on other
Bimotas. The Kb4RC allow the Bimota enthusiasts to enjoy the wind stream on their faces as well as during the glorious past of the CafèRacers bikes. Five-spoke forged alloy sport wheels and performance tires (Pirelli SportEvo) promote the Vintage Inspired Kb4 & Kb4RC look.
“Kb4 & Kb4RC will appeal to enthusiasts of all ages because the design draws you in, and the performance keeps you there,”
Borghesan said. “The Bimota Vintage Inspired has the soul for spirited, functional motorcycles. Kb4 & Kb4 RC bring the best of both worlds to the extreme, two spirited Italian Icons with a functional engine and electronic package.”
The more practical side of the Bimota Kb4 & Kb4RC includes a comfortable real leather seat. All the electonic controls are optimized for every condition which the Kb4 & Kb4RC will operate. “We have been overwhelmed by the positive public and dealer response to the Kb4 concept,” Marconi said. “The collective response from motorcycle’s enthusiasts across the world was beyond our wildest expectations.
Bimota will fan the flames of that excitement because our production Kb4 & Kb4RC won’t be watered down; they will look strikingly similar to the concept Kb4 that played to rave reviews.” The production version of Bimota Kb4 & Kb4RC, to be based off of an actual Kawasaki platform, will conceal behind a Dashboard mounted on a Carbon fiber structure, all controls for riding datas, as well as Kawasaki’s electonics devices.
“Bikers from 6 to 80 will turn their heads when Kb4 & Kb4RC come down their street,” Marconi said, “just as they did with the ’78 Kb1, the ’81 Kb2 and the ’83 Kb3. The kb4 &Kb4RC recall the fun part of Bimota’s proud history.
Oozing Bimota heritage, the Kb4 & Kb4RC are destined to become the next heart-pounding Bimota Vintage Inspired.

2026 Bimota KB4RC Guide Totalmotorcycle.com Features and Benefits
Engineering Excellence Meets Striking Design
Engineering and functionality in every detail
Every component of the KB4RC has been developed to maximize functionality and minimize weight: the 1,043 cm3 Kawasaki in-line four-cylinder engine, the Brembo braking system that offers excellent stopping power and the eccentric to adjust the height of the bike integrated into the aluminum alloy swingarm.
Customizable adjustments for a tailored riding experience
The rider can make numerous adjustments to customize the KB4RC. The suspension, both front and rear, is fully adjustable and guaranteed by Öhlins components, suitable for every riding style. The position of the footpegs can be changed according to the rider’s preferences.
Compact chassis and advanced engineering
The frame of the KB4RC is composite: the front trellis connects the engine to the steering head, two machined aluminum plates connect the swingarm to the engine, optimizing rigidity and compactness.
Extreme agility and perfectly balanced weight
Thanks to a short wheelbase and a long swingarm, the KB4RC offers exceptional handling. The radiator under the seat allows the engine to be positioned further forward, thus achieving an extremely efficient front-rear weight distribution.
Inexhaustible engineering elegance
Each and every Bimota bike is designed and assembled by hand in our spiritual home and workshop in Rimini.
