I want to buy a cross-country motorcycle recently. Please talk about the difference between ejector and chain machine in detail. What are the advantages and disadvantages? What kind of fuel economy? Thank you for your hard work. At present, only Honda's engine in China is better than 200,000 km 6 oil1; The quality of accessories is reliable and the price is appropriate. 2. After sale, 3. Quality is the most important. Suzuki and Jialing are also good, but some parts of the accessories are difficult to match and belong to tenderness.
