- Honda CBR250
The Honda CBR250 series of bikes were produced between
1986 and1996 . They were a lightweight 4-cylinder, 4-stroke, and 6-gear sportbike capable of revving up to 18,500 rpm. The earlier models (1986-1993) produced 45 ps (34 kW), from then on, the power output was reduced to 40 ps (30 kW) in 1994 after a change inJapanese law .The chronology of the models is as follows:
Despite Honda claims of the RR engine revving to 18,500 in the manual, the reality is that the ignition cuts out at around 17,230 rpm, and the ignition map is retarded around the powerful revs (14,000 to 16,000 rpm) to limit the
horsepower to Japanese law. These bikes were only ever sold new inJapan , and later the CBR250RR was sold new inAustralia . They however can be found in almost any country of the world, and in a number is the most powerful 4-stroke bike a learner is allowed to ride, and hence their popularity. Riding a CBR250RR in 6th gear at 100 km/h (60 mph) the engine revs at around 9,000 rpm. The CBR250R has five gears, and revs around 9,000 rpm at 100km/h. Despite the high revs, the bike requires little maintenance, and should easily last 100,000 km with regular oil changes (over 1/2 a billion revolutions).All four of the major Japanese motorcycle manufacturers produced a high-revving, 4-cylinder, 4-stroke motorcycle capable of producing 45 hp (34 kW). They are the
Honda CBR250, Kawasaki ZXR250,Suzuki GSX-R250 and the Yamaha FZR250.
