Motorcycle fuel overconsumption
The engine's fuel consumption curve is hook-shaped, with the lowest fuel consumption in the medium speed range. Medium speed generally refers to 3000-4000 revolutions per minute. Below this speed, the reduced air-fuel mixture flow rate leads to uneven mixing and poor combustion, resulting in increased fuel consumption. Above this range, in order to fully utilize the engine's maximum power, the engine carburetor supplies a richer fuel mixture, also increasing fuel consumption. Based on this principle, keeping the speed within the medium speed range will inevitably save fuel. Check Direction Possible Cause Solution Usage Aspects 1. Frequent overloading Correct bad habits 2. Not driving at the economical speed Improve driving habits 3. Using incorrect fuel grade Use according to the manual 4. Fuel system leakage Repair the fuel system Engine Aspects 1. Mixture ratio is too rich Adjust the carburetor or clean the air filter 2. Insufficient engine power Repair according to insufficient power failure 3. Clutch slippage Repair according to clutch slippage Driving System 1. Excessive driving resistance Check tire pressure and repair bearings and brakes 2. Inappropriate gear ratio Adjust the appropriate final gear ratio

Shock absorber oil performance and usage
Motorcycle usage time and environmental temperature vary. Therefore, to adapt to various climatic conditions in different motorcycle operating regions, most shock absorbers absorb impact and vibration energy through the flow damping force of oil and convert it into heat dissipation. Therefore, the damping force is closely related to the viscosity of the oil, and the viscosity of the oil varies with temperature. The following technical requirements are put forward for shock absorber oil: (1) Shock absorber oil must have good anti-rust and anti-wear properties; (2) Shock absorber oil should have minimal vaporization loss within the entire operating range of the motorcycle (including high-speed, full-load, and overloaded driving), also known as low vaporization performance; (3) When shock absorber oil comes into contact with air, it must have oxidation resistance and oil-gas mixture stability, also known as good operating stability; (4) The pour point of shock absorber oil used in China must not be lower than -40℃. That is, when the temperature drops to 0℃～-40℃ in the severe winter, the oil should not lose its fluidity; (5) Because shock absorber oil containing impurities will quickly scratch the piston rod or cause damage to the oil seal edge during motorcycle driving, resulting in oil leakage. Therefore, the shock absorber oil must be kept absolutely clean; (6) Shock absorber oil must not only have good viscosity-temperature performance and a high viscosity index, but also a low freezing point. When the ambient temperature changes or the oil temperature changes with the extension of working time, the viscosity change of the oil should be very small. In summary, the viscosity of the shock absorber oil has a great impact on the performance of the shock absorber. If the oil is too viscous, the soft shock absorber will become hard, and if the oil is too thin, the hard shock absorber will become soft. To change the damping performance of the shock absorber, the grade of shock absorber oil can be changed, but the amount of oil added must not be arbitrarily increased or decreased.

Motorcycle Sales Ranking for January-February 2025
Recently, the China Motorcycle Chamber of Commerce released sales data for fuel motorcycles in China from January to February 2025. According to statistics, the sales volume of fuel motorcycles in China from January to February was 2.5184 million units, a year-on-year increase of 16%. Among them, the top 10 motorcycle manufacturers in China sold a total of 1.422 million units from January to February, accounting for 56% of the industry. So who are the top 10 motorcycle manufacturers nationwide? First Tier: Manufacturers with sales exceeding 200,000 units The top-selling manufacturer is the Da Changjiang Group from Jiangmen, Guangdong Province, which mainly produces Haojue and Suzuki motorcycles. In the first two months of 2025, Da Changjiang Group's sales reached 320,900 units, the only manufacturer with sales exceeding 300,000 units. Loncin Motorcycle from Chongqing had sales of 266,600 units during the same period, ranking second in the industry. It is worth mentioning that at the end of 2024, Loncin Motorcycle merged with Zongshen, and the combined sales of the two companies from January to February exceeded 400,000 units, surpassing Da Changjiang Group. Second Tier: Manufacturers with sales exceeding 100,000 units In January and February 2025, three fuel motorcycle manufacturers had sales between 100,000 and 200,000 units. Among them, Zongshen Motorcycle's sales were 153,900 units, ranking third in the industry. Daye Motorcycle from Guangdong Province achieved sales of 141,800 units during the same period, ranking fourth in fuel motorcycle sales. Another motorcycle giant in Chongqing, Chongqing Yinxiang, had sales of 114,000 units from January to February, ranking fifth in the industry. Overall, the top five manufacturers are all from Guangdong and Chongqing, the two major motorcycle manufacturing provinces and cities. Third Tier: Manufacturers with sales below 100,000 units Xin Daizhou Honda Motorcycle from Jiangsu Province is the sixth largest motorcycle manufacturer in China, with sales of 97,400 units from January to February. Luoyang Beifang Company, from the Luyu motorcycle sector, had sales of 79,600 units during the same period, ranking eighth in the industry. In addition, Guangzhou Haojin (sales of 90,000 units from January to February), Jiangmen Zhuofeng (79,000 units), and Wuyang Honda (79,000 units) all entered the top 10. These three motorcycle manufacturers are also from Jiangmen and Guangzhou, Guangdong Province, demonstrating the strong manufacturing capabilities of Guangdong's fuel motorcycle industry. Overall, China's fuel motorcycle industry is still experiencing steady sales growth, which presents good development prospects for domestic motorcycle manufacturers. However, in comparison, the sales volume of electric motorcycles during the same period was 456,900 units, with a year-on-year growth rate of 33.55%, twice the growth rate of fuel motorcycles. This shows that domestic traditional fuel motorcycle companies need to pay attention to the impact of electric motorcycles on the industry, as their penetration rate is constantly increasing. Among them, Yadea Group, the leading company in the electric motorcycle industry, had sales of 180,000 units from January to February, becoming a force that cannot be ignored in the motorcycle industry. For traditional motorcycle manufacturers, the domestic market is gradually becoming saturated and is being rapidly eroded by new energy motorcycles. To maintain good sales growth in the future, in addition to transforming and focusing on new energy motorcycles, they also need to pay more attention to emerging motorcycle markets in Southeast Asia, Africa, and Central and South America.
