Why are there more and more motorcycles with two-cylinder engines in Japan?

At present, the domestic motorcycle market is very rich in brands and models, only in the form of various cylinders, but also in their own way, each with its own fans. Fans of single-cylinder and multi-cylinder cars are even more distinct. The "straight quartet" looks down on those who ride single cylinders, while some in double cylinders only recognize the "Boxer Rebellion" and so on. After years of precipitation, multi-cylinder cars are basically two-cylinder, three-cylinder and four-cylinder as the mainstream, and production models with more than six cylinders are rare. At present, the most models are single-cylinder cars and double-cylinder cars. Therefore, there are always many netizens who will ask, is the motorcycle with the same displacement class good with single cylinder or double cylinder? Is the number of cylinders the first requirement for you to choose a motorcycle?

Two-cylinder engine

Double-cylinder machines are divided into parallel double cylinders, V-shaped double cylinders and opposite double cylinders, with different angles and directions. We often have parallel double cylinders, vertical V cylinders and flat angles.

Parallel twin cylinders are the most common, and domestic manufacturers are basically using parallel twin cylinders for medium-displacement vehicles. For example, KE500 engine produced by Longxin is widely used in many brand models, and the market response is very good. Its biggest advantage is that it balances the characteristics of single cylinder and multi-cylinder, with lower cost and reduced vibration and noise.

V-type twin-cylinder is often used in domestic Prince or cruise vehicles, and its cost and structural complexity are higher than that of parallel twin-cylinder and its noise is also higher, but its advantages are that it can lower the center of gravity of the vehicle, with stronger low torsion and less vibration. Moreover, at present, most V-type twin-cylinder vehicles are air-cooled to dissipate heat, and leg roasting in summer and low-speed rear cylinder heat dissipation are also problems that cannot be ignored.

Opposed twin cylinders and opposed engines may be just a luxury for many people. Rarity and individuality are what boxer engine pursues. To put it bluntly, BMW's opposed twin cylinders are to retain BMW's classic charm. It has many disadvantages, such as high research and development cost, need to consider the bending of the cylinder head, and extremely troublesome maintenance. Its unique shape, ultra-low center of gravity and BMW's adjustment skills are its unique advantages, or its greatest advantage is that it is mounted on a BMW motorcycle.
