Honda CBR 250: specifications, reviews

The Japanese Honda CBR 250 motorcycle was developedconcern "Honda" in 1986 as a sports superbike with high dynamic characteristics. The relatively small displacement of the engine cylinders made it possible to develop a capacity of 45 liters. with., which provided the car a good sprint at the start, as well as high maneuverability in urban conditions.

Update

The release of the Honda CBR 250 motorcycle continued to1996, after which the production of the popular bike was transferred to the low-series 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 was 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 characteristic of which differed significantly from the parameters of the previous model, was forced again to win its place in the market. And I must say that the updated sportbike did not take much time for this, the demand for an economical motorcycle was high.

Modifications

For ten years of production, the base model of HondaCBR 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 motorcycle frame number began with the MC14, this indicated the presence of a semi-fairing, an indivisible front headlight and a double disc on the front brake.

• Modification in 1987, the chassis number begins with MC17 - a full fairing is installed on the motorcycle.
• Version 1988, number MC19 - double disc front brake replaced by a single increased diameter.
• Modification of 1989, MC21 - the changes are insignificant. The injector is equipped with a regulator that limits the speed of the motorcycle within 185 kilometers per hour.
• 1991, chassis number starts with MC22 -the changes are substantial, the model undergoes restyling. There is a new frame made of composite aluminum, more rigid and technological. The front brake is again a two-disc, but the diameter is increased to 276 mm. The pendulum-pendulum rear suspension receives a swing amplitude within 180 millimeters. Spoke wheels are changed to 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 design changes, but the color gamut of the motorcycles produced is significantly expanded.
• Version 1994, frame number of the lastmodification of the Honda CBR 250 begins with MC23. Cardinal changes touched the engine, reduced power from 45 to 40 liters. with., in connection with the law that appeared in Japan on the conformity of the cubature of engines of their power.

Responses of owners

For the entire period of production of Honda CBR sportbike250 more than one thousand motorcycles have left the assembly line. It is characteristic that there were practically no negative feedback on the quality of assembly from buyers. Honda CBR 250, reviews on which the overwhelming majority were positive, is one of the most popular models of the second half of the last century.

Owners of sportbike in the first placeits high speed characteristics. Knowingly engineers of concern "Honda" have found it necessary to limit the speed of the car by partially blocking the fuel supply. Otherwise, the bike easily picked up 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 positiveopinion on the economics of the motor. With impressive dynamics, unprecedented acceleration and high revs, the four-cylinder engine consumed slightly more than four liters of fuel for every hundred kilometers. The gasoline tank, with a capacity of only 13 liters, allowed to drive without refueling about four hundred kilometers, which is a kind of record for the sportbike.
