The Honda CBR250 series of bikes was produced between 1986 and 1996. It was a lightweight 250 cc (15 cu in) 4-cylinder, 4-stroke, and 6-gear sport bike capable of revving up to 19,000 rpm. The earlier models (1986-1993) produced 45 PS (33 kW). From 1994 on, the power output was reduced to 40 PS (29 kW), after a change in Japanese law
Initially these bikes were only sold new in Japan, and later the CBR250RR was sold new in Australia. But they can be found in almost any country of the world. In countries which have a 250cc learner capacity limit, the CBR250RR is one of the the most powerful 4-stroke bikes a learner is allowed to ride, hence their popularity.
