The Honda CBR400, also known as the CBR400R, was a small-capacity Japanese domestic market sports bike part of the CBR series first introduced in 1983 as the first Honda motorcycle that featured the CBR badge.
In 1987, the Japanese motorcycle manufacturer launched the Honda CBR400R, also known as Aero or Jellymould, as it shared its major design features with the rest of the early CBR600F and CBR1000F Hurricane family of machines that included significantly rounded body styling.
The later 1998 CBR400 model was designated as the CBR400RR, which was also known as the Tri-Arm due to its racing-inspired braced swingarm, while the 1992 model was referred to as the Baby Blade replica.
The bike was equipped with a twin-spar frame that housed a 41 mm pre-load adjustable Showa telescopic fork on the front and a preload and compression adjustable Showa shock absorber on the rear for optimum suspension performance and handling.
In the braking department, the bike packed two 275 mm discs with four-piston calipers on the front wheel and one 220 mm disc with a dual-piston caliper on the rear wheel for optimum stopping power.
As for the power figures, the 1987 Honda CBR400R took its muscles from a 399cc four-stroke four-cylinder liquid-cooled engine fed by four carburetors and delivered an output power of 59 hp with maximum strength at 12,500 rpm and 39 Nm (29 lb-ft) of torque at 10,000 rpm.
