After the successful of the predessor "CBR400R 1986", Honda released the newer super sports bike "Honda CBR400RR" on January 19, 1988 that looks more sporty and racing oriented. It adopts advanced equipment such as a new fairing that combines excellent aerodynamic characteristics and a powerful form in the popular CBR series, front and rear wheel radial tires and powered by a water-cooled, 4-stroke, DOHC, in-line 4-cylinder 400cc engine that uses a cam gear train (a method of driving the camshaft with gears) mechanism.

1988 Honda CBR400RR Engine Overview
This Honda CBR400RR makes full use of the 4-cycle engine technology that Honda has cultivated over many years, and in addition to the light and smooth output characteristics that are characteristic of in-line 4-cylinder engines, it has a quick and powerful responsiveness in the middle and low speed range. Is even higher. Moreover, the basic skeleton from the frame to the swing arm to the wheels is all made of aluminum, and the aluminum muffler (silencer) is adopted for the first time as a mass-produced 4-stroke model. It is a super sports bike that combines strength and high quality.
Newly designed cylinder head, straightened intake port, direct push valve system without rocker arm, thin shaft (3.8 mm), large diameter (intake valve 22 mm/exhaust valve 19.5 mm) valve, etc. Achieves high combustion efficiency at the same time as reducing friction loss in the valve train. In addition, a large diameter (32.5 mm) quadruple carburetor and a new collective exhaust pipe are combined with a lightweight aluminum muffler (silencer) with a new structure to further improve intake and exhaust efficiency, especially in the middle and low speed range. It is designed to demonstrate the quick and powerful responsiveness of.
1988 Honda CBR400RR Frame & Suspension
The lightweight and highly rigid aluminum twin-tube frame, which has Honda's unique "eye-shaped" cross-sectional structure, has a slimmer shape and contributes to ensuring a comfortable riding posture. For the front and rear wheels, a newly designed aluminum hollow 3-spoke cast wheel is combined with wide flat radial tires (front 120/60 R17, rear 150/60 R18). In order to take advantage of the characteristics of these frames and tires, we have newly developed a triangular swing arm (tri-arm) that has both slimness and high rigidity. Combined with the front and rear suspensions that demonstrate excellent road surface tracking, you can enjoy agile and nimble maneuverability.
