A Closer Look at The 2022 Bimota KB4

2022 Bimota KB4

Bimota eventually debuted their finished Kawasaki powered retro sports bike design at the EICMA expo in Milan in late 2021, after over two years of production photographs, secret chats, and detailed information. Bimota’s selection of a Kawasaki engine is unsurprising given that the Japanese company currently owns 49 percent of the business. The 2022 Bimota KB4 was designed and produced in accordance with Bimota’s tried and true methodology of taking performance cylinders from production models and developing a top-quality motorbike around them. Bimota chose a 142bhp four-cylinder engine from the Kawasaki Ninja 1000SX for this project. However, Bimota has drifted away from the company’s (Kawasaki) sports touring approach in order to build superior handling, less weight, and significantly greater KB4 with higher specs. And, just like every Bimota, the motorbike has its own unique selling point, something that distinguishes it from the competitors. The KB4 is ideal for chilly winter mornings, and its uniqueness, aside from its looks, makes it worth a look. Let’s take a closer look at the new 2022 Bimota KB4, with some quick facts and the motorbike’s specifications.

1. The Kawasaki 1000SX Engine

The engine is the Kawasaki 1000SX engine, a 1,043 cc four-cylinder engine that produces 142 hp at 10,000 rpm and 82 lb-ft of torque at 8,000 rpm. However, in comparison to the Kawasaki, the radiator is now located horizontally under the back tail. Aside from cooling the engine, the KB4 includes side air ducts under the fairing, which give it that unusual side look. It’s also possible that the new bike will include Kawasaki’s latest ride-by-wire throttle, allowing the SX to have cruise control.

2. Öhlins TTX36 Suspension

Despite the fact that Bimota is famed for its hub-steering innovations, the 2022 Bimota KB4 features standard Öhlins suspensions. The suspension is an Öhlins upgrade option for Kawasaki Ninja ZX-10R riders, and the linkage-assisted piggyback-reservoir shock absorbers are a part of Öhlins’ premium Hypersport shock range. The suspension of the KB4 has also been modified, with a 43mm Öhlins FGRT NIX 30 fork upfront. The motorcycle is equipped with an Öhlins TTX 36 rear shock. Both shock absorbers are preload adjustable.

3. Chassis

In terms of the chassis, the 2022 Bimota KB4 has a Kawasaki Ninja 1000 motor and a trellis frame. It’s a multi-tubular elevated steel frame with several features added and made from an aluminum alloy block. These features, which are part of the KB4’s architecture, can be seen independently on the Bimota website. The Kawasaki electronics are also used on the motorcycle, albeit the dash seems to have a carbon fiber mount. In addition, the strengthened aluminum double-arm swingarm was constructed by Bimota. This improvement allows the KB4 to be significantly lighter than the Kawasaki.

4. Pirelli Tires & Brembo Calipers

The tires are quality Pirelli Diablo Supercorsa rubber, and the brakes are Brembo calipers. The Pirelli Diablo Sport radials on the 2022 Bimota KB4 are 120/70 x 17 in front and 190/50 x 17 in the rear. The motorbike will include two big 320mm discs at the front, as well as a set of Brembo Stylema brakes. The rear wheel will be equipped with a single 220mm disc. The dry weight is a reasonable 417lbs (189kg). Bimota has not revealed any information about the ABS in its new KB4.

5. Weights & Dimensions

In terms of weight, Bimota and Kawasaki are still the most divergent. The Ninja 1000SX is said to weigh 517lbs (235kg) wet, whereas the KB4 weighs 412lbs (187kg) dry. The Kawasaki Ninja and the 2022 Bimota KB4 are both compact in terms of weight and wheelbase, measuring 56.7 inches for the Kawasaki Ninja and 54.7 inches for the Bimota KB4. The length decrease was accomplished unusually. Merely reducing the swing arm would have thrown off the distribution of weight, shifting the bias rearward, which is undesirable for handling. The front end has a cutting-edge 24-degree steering axis and 101mm (4.0 inches) of the trail.

6. Quality and Comfort

Bimota focused on making the bike usable for real-world riding, with special emphasis on riding experience to its customers. The seat height is kept much more comfortable to the rider at 31.6 inches (803mm) to 31.9 inches (810mm) in order to provide a center of gravity that has to be one of the lowest in the modern sportbikes sector. The seat height can also be adjusted in any direction by 0.31 inches (8mm).
