250cc motorcycles are the most popular models in the road class. Various modifications of the brands "IZH", "Kovrovets", "Minsk" can still be found today both on the highway and on city streets. A special category is made up of motorcycles of 250 cubes for sports purposes, motocross and racing two-wheeled vehicles. Models of the Soviet period for cross-country competitions are Kovrovets, IZH, Minsk and Voskhod. There were no domestic motorcycles for road racing in the 250 class in the USSR.

Does a dynamic car need a muffler

250cc sport bikes are very different from road bikes. First of all, it is a boosted engine that allows you to develop power an order of magnitude higher than a conventional motor can give. The specificity of the competition involves the operation of the power plant of the motorcycle in extreme mode, the resource of all mechanisms is sharply reduced. To increase engine power, sports mechanics rework the exhaust system. Removed from the mufflerspecial partitions that are designed to reduce the noise of the engine. Without them, the exhaust mode becomes direct-flow, and the noise increases dramatically. Therefore, Soviet cross-country motorcycles of 250 cubic meters rattled so much, driving their distance. The measures to remake the muffler were fully justified, since by removing the mesh partitions, the engine thrust was significantly increased.

Daytime Challenges

Each 250cc motocross bike is a powerful two-wheeled machine whose mission is to always be first at the finish line. The technical condition of the structure must be perfect, both speed and maneuverability depend on the operation of components and assemblies. A motorcycle must be able to “take off” from a place and slow down in time, pick up speed and enter a sharp turn, this is the art of cross-country racing, where the roads are only unpaved and there is not a single straight section. The 250cc motocross bike does not have any lighting equipment, headlights are not needed, since the competition takes place only during the day. Turn signals are also redundant, a brake light is specified, but it is practically not needed either.

Japanese 250cc motorcycles are famous all over the world. Models that are sold as road cars, however, have a pronounced sporty character. And sports modifications are ready-made two-wheeled racing cars with a speed of more than two hundred kilometers per hour. Some models are even considered dangerous for an inexperienced rider, as they take off too quickly, and before the rider has time to siege the Mustang, he will have time to fly a hundred meters. Therefore, the manufacturer must attach detailed recommendations to the machine being sold, which are designed for careful consideration. This peculiar course of driving high-speed motorcycles at first glance seems like an unnecessary reinsurance, but in fact there is every reason for such an approach.

Some novice riders can simply get confused if the bike gets out of hand, and then the situation can end in a fall and injury. Some models from Japanese manufacturers are equipped with accelerator limiters, this is included in the pre-sale preparation. The measures are justified, as they ensure the safety of the owner of a sports motorcycle. When the rider gains experience, the block will be lifted.

Java-250

In the 1960s, an elegant cherry-colored motorcycle with chrome mufflers and a comfortable double seat appeared in Soviet retail stores. It was a Java-250, a model from Czechoslovakia. The motorcycle cost 630 rubles, which at that time was quite a large amount. The spectacular beautiful Java-250 car, the photo of which appeared in all magazines related to motorsport, immediately won the love of Soviet motorcyclists. The Czechoslovak model had no racing modifications.

Cost

Racing and motocross motorcycles, prices for which have always been kept at a fairly high level, can be purchased from the hands, the choice is very wide. Models of any year of manufacture,manufactured by Japanese and European firms. Road models are also available. But most of all, it is cross-country motorcycles that are offered, the prices for which are formed depending on the technical condition of the machine. The year of issue also matters, but in most cases this criterion is subjective. Motorcycles of 250 cubic meters, the price of which ranges from 74,000 to 420,000 rubles, are now available for purchase throughout Russia.
