Debuted at the Milan Motor Show in Italy last month, the Bimota KB4 officially announced the price today, but did not choose to start in Italy, but chose to release the price in Japan, as to why Japan can get the start, and the cooperation between Kawasaki and Bimota has a lot to do with it.
The Bimota KB4 vintage sports car costs 4,378,000 yen (245,000 yuan) in Japan, while the Ninja 1000SX with the same engine is priced at just 1,485,000 in Japan. The first models are limited to 200 units and will be delivered from early March 2022.
Bimota KB4 is a very classic retro sports car, because its design reference, Bimota last century models "KB2" and "KB3", so it looks retro, but under the retro appearance has a lot of high-tech blessings.
The car is equipped with the same 1043cc four-cylinder engine from the Kawasaki Ninja 1000SX, with a maximum power of 142ps/10000rpm and a maximum torque of 111Nm/8000rpm, but the overall weight of kb4 is 42kg lighter than that of ninja 1000SX.
The KB4 doesn't feature a unique wheel steering technique than Motta, but it has an amazing performance in terms of frame, and in addition to the heavy use of aluminum, the front and rear weight distribution methods are also amazing. Move the engine mounting position forward by installing a radiator under the rear seat. As a result, despite the wheelbase as short as 1390 mm, the swing arm length reaches 555 mm, achieving a weight distribution of 46.4% after the first 53.6%.
Moreover, the radiator under the seat can avoid the exhaust pipe from being exposed to the radiated heat of the engine, and since its structure is to drain the heat from the air ducts on both sides of the seat and suck it out under the negative pressure under the seat cover, it has a considerable cooling effect when running.
The KB4 is also electronically available in a full-color TFT meter with IMU (Inertial Measurement Unit), Turn Management Function (KCMF), Traction Control (KTRC), Power Mode, Quick Shift (KQS), Electronically Controlled Throttle Valve (ETV), Cruise Control, ECO Indicator, Auxiliary and Sliding Clutch.
Chassis section, 320mm dual front disc with Brembo monocoque calipers, rear 220mm single brake discs with Brembo single-piston calipers. There are also forged aluminium rims and Pirelli Diablo Rosso III tires. Front and rear suspensions are supplied by Ohlins with FGRT 43 NIX30 inverted forks and TTX36 mid-mounted rear suspension.
The design from Italy and the numerous lightweight technologies make the Bimota KB4 full of unique charm, and Kawasaki does not have the same style model on the same platform, so even if the price is much more expensive than the Ninja 1000SX, it will not conflict with Kawasaki's model.
