Buying a car is a major event in life. I believe everyone will search for a lot of information on the Internet before buying a car. The specifications and data of motorcycles are often published on the websites of major car manufacturers and media. In fact, this specification data sheet will provide you with a lot of information for you to judge whether this motorcycle meets your needs. Today, Wang Li, the helmet, will teach you how to read the specification sheet of the new car, so that you can choose the motorcycle that meets your requirements more efficiently! If you have friends who are planning to buy a car, remember to share this article to compare them!

Body size/weight

First of all, the information that must be included in the specification sheet of a new car includes car body size related data such as car length, car width, wheelbase and car weight . The length and width of the vehicle will mainly affect the flexibility of a motorcycle and the difficulty of finding a suitable parking space. In addition, for a motorcycle with a wider body, even if the seat height is not high, it will be more difficult for the rider's feet to touch the ground.

As for the wheelbase and vehicle weight, these two figures will mainly affect the flexibility and stability of a motorcycle. A motorcycle with a shorter wheelbase has a smaller turning radius and more flexible response in corners. Motorcycles with a long wheelbase have better stability in a straight line, and each has its own advantages and disadvantages. As for the weight of the car, the heavier the car, the more energy the rider needs to expend when parking and pulling the car. Motorcycles with a higher weight will have better stability when cruising in a long straight line and are less susceptible to crosswinds. There may be obvious differences when driving on roads such as Tsing Ma Route and Ting Kau Bridge. The benefits of light weight are very obvious. In addition to being easier for the rider to move the motorcycle, the driving experience will also be relatively flexible.

Engine (number of cylinders/displacement)

In terms of engine form, there are three key points that you can pay attention to before buying a car. One is the number of cylinders of the engine, which is commonly known as the "cylinder" in single-cylinder cars and four-cylinder cars. For the impact and difference of the number of cylinders on the tonality of motorcycles, you can refer to this article published by Helmet King earlier , which has a more detailed and complete introduction.

The second important thing to pay attention to is the displacement of a motorcycle. The larger the displacement, the higher the horsepower, price, and maintenance costs of the motorcycle. In foreign countries, the higher the displacement, the higher the taxes related to motorcycles, but there is no similar regulation in Hong Kong. However, if there is no special pursuit of horsepower and performance, cars with a displacement of less than 700c.c. in general in Hong Kong are quite sufficient.

Horsepower output

As mentioned above, horsepower output usually increases with higher displacement, but this is not absolute. Even though the displacement of the Big Yang car is larger, due to the adjustment of the engine by the car manufacturer, the positioning of the model, and the transmission form and many other differences, the horsepower may still be higher than that of the wave car with a smaller displacement. Small. The sports car model is positioned to focus on performance, so the horsepower output is usually higher. Behind the larger horsepower output, it means that it will be more difficult for the rider to drive the motorcycle, and the fineness of the throttle control will be higher.

In addition, in addition to the maximum horsepower on the specification sheet, you can also pay attention to the high speed at which the maximum horsepower will be fully displayed. Although the maximum horsepower of a sports car model is higher, it usually requires a higher speed to be fully released. In fact, there are certain doubts about whether there is a way to achieve high speed to maintain high horsepower output on ordinary roads. Although the maximum horsepower of a street car may be lower, it can usually be achieved at a lower speed, which may be more suitable for the road environment in Hong Kong. Therefore, when buying a car, you don’t have to pursue the bigger the horsepower, the better. Choose a car model that suits your horsepower and displacement level, which can make your economic burden on owning motorcycles and motorcycles even less. pressure.

Torque output

Many riders have heard of it and can understand the concept of "horsepower", that is, the greater the horsepower, the faster the motorcycle. But many riders are not familiar with the concept of "torque". Simply put, an engine with greater torque can lift heavier objects (whether it is the motorcycle itself or the goods carried by the motorcycle). The greater the torque, and the car that can reach the maximum torque at a lower speed, the better the strength and acceleration when starting. Taking the stop-and-go road environment of the market as an example, if you want to achieve a strong start and a brisk ride, sometimes torque is more important than horsepower. Due to engine adjustment, both horsepower and torque are concentrated in the high-speed range of some models. When starting frequently in urban areas, the power output of the motorcycle will be insufficient, which is caused by the lack of low-speed torque. Generally speaking, for street bikes with street riding as the main appeal and design direction, the plateau of torque output will appear earlier.

Seat height

For novice riders, the term "seat height" may sound unfamiliar, but in fact, it means the height of the motorcycle seat from the ground. Generally speaking, the seat height will be calculated in mm. Helmet King will briefly give you a reference value here. The car models below about 780mm can be regarded as relatively / relatively close to the people. It should be noted that the height of the seat usually means that the feet can easily touch the ground, but this is not absolute. For example, cars with big sheep and three-cylinder and four-cylinder engines usually have a wider width . It will be harder to hit the ground. Therefore, the seat height on the spec sheet can be used as a quick reference for whether your feet can touch the ground, but it is not absolute.

Front Suspension (Shock Absorption)

Finally, the suspension form adopted by a motorcycle will also have a certain impact on the tonality of the motorcycle, and it also reflects the positioning of the motorcycle by the car manufacturer. Car models on the market mainly use upright suspension and inverted suspension, commonly known as positive fork and inverted fork respectively. Compared with the positive fork, the inverted fork has advantages in rigidity and unsprung weight, so it is usually used in performance and sports cars. However, because the structure is more complicated, the cost reflected in the car price and maintenance will also be higher.
