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.

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.
