The Japanese Honda CBR 250 motorcycle was developed by Honda in 1986 as a sports superbike with high dynamic performance. The relatively small displacement of the engine cylinders made it possible to develop a power of 45 liters. with. that provided the car a good sprint breakthrough at the start, as well as high maneuverability in urban conditions.
Update
The release of the Honda CBR 250 motorcycle continued until 1996, after which the production of the popular bike was transferred to low-volume assembly mode, and in 1999 the conveyor was stopped. The CBR 250 was replaced by other models. However, two years later, the Honda CBR 250 began to be produced at the Honda plant in Thailand, with a single-cylinder injection engine. In principle, it was already another version of the motorcycle. The new Honda CBR 250, the characteristics of which differed significantly from the parameters of the previous model, was again forced to gain its place in the market. And I must say that the updated sport bike did not take much time for this, the demand for an economical motorcycle was high.
Modifications
Over the ten years of production, the base model of the Honda CBR 250 has undergone a number of changes, seven different modifications have been released. The classification of each new version was determined by the index in the digital chassis set. For example, when the number of the motorcycle frame began with MC14, this meant the presence of a half fairing, an indivisible headlight and a double disc on the front brake.
- Modification of 1987, the chassis number starts with MC17 - a full fairing is installed on the motorcycle.
- 1988 version, MC19 - double disc front brake replaced by a single larger diameter.
- Modification of 1989, MC21 - minor changes. A regulator is installed on the injector, limiting the speed of the motorcycle within 185 kilometers per hour.
- 1991, the chassis number begins with the MS22 - significant changes, the model is being restyled. A new composite aluminum frame appears, more rigid and technologically advanced. The front brake is again double disc, but the diameter is increased to 276 mm. The articulated-pendulum rear suspension receives a swing amplitude within 180 millimeters. Spoked wheels are replaced by cast aluminum. The dry weight of the motorcycle is reduced from 148 to 142 kilograms.
- Modification of 1993, chassis number MC22-E. There are no constructive changes, but the color gamut of the coloring of manufactured motorcycles has been significantly expanded.
- The 1994 version, the frame number of the latest modification of the Honda CBR 250, starts with the MC23. Dramatic changes have affected the engine, reduced power from 45 to 40 liters. with., in connection with the law in Japan on the compliance of the cubic capacity of engines of their power.

Owner feedback
Over the entire production period of the Honda CBR 250 sport bike, more than one thousand motorcycles left the assembly line. It is characteristic that there were practically no negative reviews on build quality from buyers. Honda CBR 250, the reviews of which were overwhelmingly positive, is one of the most popular models of the second half of the last century.
Owners of a sport bike primarily note its high speed characteristics. No wonder the engineers of the Honda concern considered it necessary to limit the speed of the machine by partially blocking the fuel supply. Otherwise, the motorcycle easily gained more than 200 kilometers per hour. And this was a direct violation of the law on restrictive measures that apply to sports bikes with an engine capacity of up to 250 cubic centimeters.
Many owners expressed their positive opinions regarding the efficiency of the engine. With impressive dynamics, unprecedented throttle response and high speeds, the four-cylinder engine consumed a little more than four liters of fuel for every hundred kilometers. The gas tank, with a capacity of only 13 liters, allowed to drive about four hundred kilometers without refueling, which is a kind of record for a sports bike.
