Honda CBR400RR is popular as a high-performance yet easy-to-use super sports bike equipped with Honda's original cam gear train (a method of driving the camshaft with gears) mechanism, water-cooled, 4-stroke, DOHC, in-line 4-cylinder engine. This series was remodeled and released on March 19th, 1990. It looks more proper with better design and body works compared to the predessor (old CBR400RR 1st generation.

This 1990 Honda CBR400RR has "high-dimensional human fitting" as the development keyword, and in order to show a more straightforward ride to the rider's operation (combined movement such as acceleration, deceleration, cornering), put a heavy object in the center of gravity of the car. In addition to bringing it closer, we thoroughly pursued the concentration of inertial mass (mass) by reducing the weight of the part far from the center of gravity, and the engine, frame, suspension, etc. are all newly designed.

The Honda CBR400RR's engine has a completely new intake/exhaust system, such as arranging the air cleaner, carburetor, and intake port almost linearly. At the same time as improving efficiency, powerful torque characteristics and agile responsiveness are realized by adopting a map control type PGM ignition that can set and supply the optimum ignition timing according to the accelerator opening and engine speed. ing. In addition, the cylinder and upper/crankcase are integrated, and the main transmission shaft is located near the center of gravity to thoroughly pursue light weight, compactness, and mass concentration, which greatly contributes to improving the degree of freedom in frame design.

The frame and suspension are made of aluminum LCG (LOW CENTER OF GRAVITY, meaning low center of gravity) with a novel style newly designed according to the compact engine shape, and a lightweight and highly rigid large diameter (41 mm) front. -Forks, new-shaped aluminum rear forks (castec gull arm) that can efficiently lay out exhaust pipes while ensuring high rigidity, and lightweight 6-spoke aluminum wheels (front/rear) that reduce the amount of underspring. Equipped with a combination of 17-inch diameter). By centralizing the mass of the entire body and suspension and setting the center of gravity exquisitely, a maneuvering feeling that responds more honestly to the rider's sensibility is realized.

In addition, a direct air intake that distributes the outside air in three directions is adopted, and in addition to the air cleaner and the rear of the engine, the outside air is also introduced to the rider's knees, improving efficiency and comfort at the same time. ing. In addition, a storage space that allows one-touch opening and closing (hinge type) of the rear seat with a key operation, dual halogen headlights (60/3 5W x 2) with wider light distribution during low beam, and a loading hook. It is also equipped with equipment that improves usability, such as a retractable pillion step that can also be used.

This time, the body color is set to two colors, a tricolor (white / red / blue) color with a youthful and refreshing image that adopts a bold and dynamic brush pattern, and a black with a fearless and firm image. Combined with the "CBR" brush character logo on the side of the car body, the sportiness is further enhanced.
