The Honda CBR250F is a CBR series 249 cc (15.2 cu in) four-cylinder sport bike made by Honda. The CBR250F was first sold in Japan in 1986.^[1] The CBR250RR MC22 was discontinued in 1996 in Japan, but sales continued in Australia until 2000^[2]

Overview

The CBR250F aka CBR250 Four was made in 1986. Motorcycle racing was popular at the time, with the Japanese Grand Prix and Suzuka 8 Hours drawing large crowds. Licensing restrictions in Japan also caused small displacement motorcycles to have a bulk of the motorcycle sales. Thus, the CBR250F sport bike was born.^[3]^[4] Other Japanese manufacturers would also design 250cc 4 cylinder sport bikes, such as the Suzuki GSX-R250, Yamaha FZR250, and Kawasaki ZXR250.
