Motorcycle is a convenient and fast means of transportation, also used in military and sports competitions. It has an internal combustion engine. It is divided into two-wheeled and three-wheeled motorcycle stand. Motorcycle has a history of more than 100 years since its birth. Tracing back to the origin, the first motorcycle in the world belongs to a two-wheeled motorcycle powered by a steam engine, which was made in 1869 by Pierre Weishaw, a Frenchman. Motorcycles powered by gasoline engines were invented by Daimler in 1885 and named "Monorail Number". The engine displacement is 264 ml, the power is 0.37 kw and the speed is 12 km/h. This engine is single cylinder, air-cooled and two stroke.
If the large-scale heavy machinery was mentioned in the 1960s and 1970s, it was generally the high-level handlebars. It has a vertical driving posture above half-body, with straight cruise as the priority design. Different from the driving posture of the upper body erect before the 1970s, it has become a suitable driving posture for sports driving since the 1980s.
In the 1960s, most motorcycles were designed with water droplets. Short fuel tanks were the mainstream at that time, while long fuel tanks were regarded as the symbol of sports cars. Since the 1980s, mass-produced vehicles have gradually adopted the long version design. The representative model is CB750F, which appeared in 1979.
When the fuel tank design is lengthened, the pedal also gradually recedes with the times. The pedal, which was originally set near the front teeth disc, gradually moved behind the motorcycle bolts. The seat also moves backwards, turning into a forward-leaning driving position.
In the early 1980s, the leading position of the imitation racing car was relatively high, and the design of the head was completely different from that of the present sharpness. Along with the evolution of the times, the position of the head decreases, while the shape of the head becomes more streamlined.
Although the posture in the 1980s was quite forward, it was because linear acceleration was the priority at that time. In view of the present Shuihuai River, the performance of tires and brakes is unexpectedly poor. In addition, many WGP competitions are held on the highway, and the road surface is quite uneven. Bend performance is not paid attention to. Although the posture is also forward leaning, it is different from the current consideration based on over-bending.
The shape design of fuel tank is mainly based on stabilizing arm.
In recent years, overrunning in the design of fuel tank shape will be mainly driven by side-hung and over-bending posture. This fits the ergonomics of the arm and makes the body more stable. This kind of design method, which is mainly over-bending, was unexpected before the 1980s.
With the progress of society and science, in order to make people better use, motorcycle wheel design is more and more in line with people use habits. This has brought great convenience to people. We are a factory engaged in producing motorcycle bolts, motorcycle stand and wheel chock, motorcycle tie down, motorcycle tool, and plastic can.
