In terms of motorcycle business, it has the ability to independently design a full range of models such as scooters, street cars, sports cars, riders, and electric vehicles. It is also a rare domestic motorcycle company with independent electronic injection technology, and can carry out large-scale production. The company has a water-cooled multi-valve airway to optimize the technical combination of independent EFI, so that in the small and medium-sized displacement to achieve high performance, low emissions of the dual gain, in the V-cylinder segment has maintained a special competitiveness and market position. The products have entered Asia, Africa, South America, Europe and North America and other countries, with thousands of retail service outlets in China, and a user-centered full-process closed-loop online service operation mechanism has been established. At present, it has the ability of continuous sales and service.

It is also one of the few domestic motorcycle companies with independent electronic injection technology, and has achieved large-scale production goals. The company has a water-cooled multi-valve airway to optimize the technical combination of independent electronic injection, so that in the small and medium-sized displacement to achieve high performance, low emissions of the dual gain, in the V-cylinder subdivision line constantly maintain a unique competitiveness with the market position. Products have entered Asia, Africa, South America, Europe and North America and other countries, the domestic layout of thousands of retail outlets, and the user-centric full-process closed-loop online service operation mechanism system has been established, it can be said to have continuous sales and service capabilities.

We often use cleaning agents in the process of motorcycle repair and maintenance. Commonly used cleaning agents include carburetor cleaning agents, throttle cleaning agents, asphalt cleaning agents, chain cleaning agents, rust and decontamination agents. I 'd like to introduce their use methods and taboos. Don't think that they are all cleaning agents. If you use them indiscriminately, you will not only fail to achieve the effect, but will have a counterproductive effect.

Cylinder air leakage and slight air leakage in the engine can also cause unstable idling speed of the motorcycle. There are many reasons for air leakage, such as too tight valve clearance, poor sealing of the carburetor and cylinder block connection, and secondary combustion pipe Damage and other damage will cause engine air leakage

Yamaha r3 inherits the front face design of R series in appearance, which is more iconic. In addition, in terms of the performance of the car, a 321cc displacement two-cylinder water-cooled engine is used, and its horsepower can reach 41 horsepower, and the torque can reach Nm. However, it should be noted that this motorcycle is not equipped with Yamaha VVA's variable valve technology.

Unequal pitch coil springs are used for suspension springs and high-speed engine valve springs for motorcycles and small passenger cars. On the same spring, it can not only meet the small stiffness when the deformation is small, but also meet the requirements of large stiffness when the deformation is large. The unequal pitch spring can meet these requirements.
