After the defeat of Japan and the two resistance countries, Germany and Italy, in World War II, they were barred from conducting research, development, design, and aircraft production until the late 1940s, and this gap coincided with the advent of the jet engine. And the emergence of opportunities for other nations to enter the modern age of air travel. As a result, the best Japanese engineers and mechanics were not sent to design and manufacture aircraft and even make repairs on them, and therefore the attention of the Japanese thinkers turned to the design and production of automobiles and motorcycles.
Motorcycle group and class and type of use
When buying a motorcycle, whether new or second-hand, what you should always consider is how to use it and the type of use it means, whether you want to have an agile motorcycle for daily use on the streets and city roads or you are looking for a motorcycle. With which you do not hesitate to make long trips and prefer a combined ride off-road and that river with a road
Propulsion is the most important part of a motorcycle and in fact it is the heart of it. When following and searching for propulsion, the things that should be considered are engine volume, number of cylinders and their arrangement, type of valve and valve stem, cooling system, how Power transmission and finally the fuel system.
The amount of propulsive power produced
The diameter and stroke of the piston, the number of cylinders, the arrangement of the cylinders and a myriad of other factors determine the amount of power produced and the propulsive torque The contract is placed next to the weight of the motorcycle while its fuel tank is full
Dimensions, size and weight
To better understand the ride quality and performance of a motorcycle, you can refer to factors such as weight, dimensions and size of the motorcycle. Heavier motorcycles are more stable, especially at high speeds. It should be noted that a motorcycle with a larger engine needs a larger and heavier chassis and frame, larger brakes and a stronger suspension system, all of which lead to weight gain. Another thing that should be considered in this section is the height of the seat from the ground.
Since the propulsion of a motorcycle is responsible for moving it, the capabilities of the braking system and the ability to cross the circle of turns are related to the parts that are equipped with them. For this purpose, many buyers of motorcycles want to deal with parts and components such as suspension system, hardware related to the braking system and many sub-parts, but at the same time important such as cornering, steering and how to adjust it, lights and wheel rims before buying Become familiar . Apart from the propulsion of other components, they play a key role in shaping the motorcycle.
Technology and rider support items
Over the past decade, the motorcycle industry has made tremendous leaps and bounds in the advancement of technology, and the use of electronic equipment that supports riders and prevents them from getting involved has greatly increased. These technologies were first used in expensive racing engines and are now used in non-racing types as well, including controls related to engine braking and wheel slip, anti-lock braking system in passing corners and Finally, systems that are directly involved in the production and transmission of power to help the rider to make the best use of 200 horsepower of production power. Today, many large motorcycles are equipped with LCD or TFT displays, active suspension system, electronic throttle lever and various driving modes.
Performance and efficiency in the real world
Refer to the technical specifications of a motorcycle when buying, such as production force, weight and acceleration can be largely a function of its performance and efficiency, but nothing can replace the riding experience with them before buying, and for this purpose it is recommended before From buying a motorcycle, do a riding test with it.
Price and value
Motorcycles manufactured in Japan today offer more features than European competitors without compromising on performance compared to European competitors manufactured in Germany, Austria and Italy, such as price differences. $ 10,000 with less can be attractive to buyers.
Top 8 Japanese Motorcycles Recently Launched
Honda Rebel 300
Since its launch in 1985, the Honda Rebel or 250 CMx has been one of the most popular small cruisers. In 2016, Honda decided to increase the engine size of this model, and with it, made general changes in the design in order to be more modern. The Rebel 300 is a motorcycle with a short seat height of 69 cm and a weight of 166 kg and a wheelbase of 149 cm, which makes it an ideal motorcycle for inner-city travel and daily use. Its propulsion is a single-cylinder cold water type in which injector refueling is performed and it is equipped with two valve shafts at the top and it is also offered in models with volumes of 471 cc to 500 Rebel and volume of 1084 cc called 1100 Robol. The production capacity of the 300 model is 27.5 hp with 20 torque and a maximum speed of 145 km / h.
Suzuki DR – Z 400SM
This Suzuki was one of the most popular dual-purpose sports models, first introduced to the market in 2000, and its great popularity is due to its appearance, performance and performance, reasonable price and extraordinary reliability. In 2005, changes were made to the suspension with more adjustable suspension, new water-cooled propulsion, and smaller tires for better city travel, which eventually led to the production of the DR-Z400SM, a versatile motorcycle. It can be turned into an off-road simply by changing its rims and tabs to a larger model. It produces 39 horsepower with 29 pound-feet of torque, a top speed of more than 150 km and a weight of about 146 kg.
Following restrictions on engine size, which reached 400 cc, the Japanese motorcycle market, which had previously produced ultra-powerful motorcycles, began producing low-volume multi-cylinder models. One of these motorcycles is the Kawasaki ZX-25R, which, unlike other models on the market, this Ninja with a quarter-liter engine is equipped with a 4-cylinder in-line water-cooled engine with a maximum engine speed of staggering. It does 17,000 rpm, which is not bad for information and comparison. Know that this engine is 2,000 rpm faster than a modern and modern Formula One car. Despite the small volume of the engine, but in terms of equipment, facilities and technology, it is completely equal to one-liter engines. Wheel, which can be used as an engine brake if needed, and the engine produces 43.5 hp with 6.15 lb-ft of torque and a top speed of 188 km / h.
Names TENERE 700
Undoubtedly, it is one of the most important models that has attracted motorcycle enthusiasts in recent years.

Its maximum speed is more than 262 kilometers per hour and it is 190.5 kilograms
Kawasaki Z H2
Although pressure induction drives are very common in the automotive world, this technology has not yet been used in the motorcycle world. But that changed with the introduction of the Kawasaki Supercharger Ninja H2 in 2015. While it was undoubtedly a different model, the H2 was available for $ 29,000 for a limited number of interested parties, so Kawaski officials announced that the cheaper version, which had fewer parts but was equipped with a supercharger, was called the H2 2. Those who are interested will offer.
Apart from producing 200 hp and 100 lb-ft of power, this motorcycle also features electronic cruise control, various riding modes, turn-by-turn management technology, Launch control for quick start, communication with a smartphone, The clipper of the Slipper type that was mentioned, and finally the excellent type of two front branches made by Showa.
