One of the most anticipated new products of Milan EICMA-2015 Moto-show will be Yamaha R3. The novelty, according to the manufacturer, will be equipped with a 321-cc engine with a capacity of 44 horsepower. It is intended to replace, or complement the model R25. Today class 250ss clearly is in decline. Japanese manufacturers, one after the other, are trying to offer the market 1-or 2-cylinder "casual" motorcycles, but they failed to revive the massive demand. Time after time these models have been developed, usually in the direction of increasing motor. In fact the major automakers, such as Honda, Kawasaki and Yamaha just could not build so simple bikes, what used to be the classic 4-cylinder 250-plastic model for moving around the city. It turned out too expensive for a simple motorcycle and too simple for the expensive one. In the end all they went through the growth of the expense, and 250ss bikes actually a thing of the past, and today all three manufacturers offer volume higher than 300. And now, Yamaha is preparing to exit the entry-level sport bike with three hundreds of cubes and, according to experts, can activate a stagnant market. Stated specifications of Yamaha R3 surpass those which had preceded R25 with 250-ccengine. Under the new, more powerful three cylinder engine liquid cooled, it will retain a modest weight not exceeding 170 kilograms. Therefore, among the main competitors it should look very confident.
