In the history of the development of curved beam vehicles, the topic of how to make power faster and more energy-efficient on the original basis has caused domestic motorcycle manufacturers to rack their brains and make various attempts, such as the " automatic wave " that appeared in sales for a period of time . New products such as transmissions and energy-saving devices on transmissions, but for some reason, these new technologies disappeared after a period of time and were not fully popularized. Among the power innovations, it is worth mentioning that in 2001 , Lifan developed and designed a small-displacement water-cooled engine with independent intellectual property rights and assembled it on a curved beam vehicle. The successful development of the water-cooled curved beam bike is a milestone in the domestic motorcycle industry, filling the gap in the domestic small-displacement water-cooled bike, and even surpassing the technical level of foreign counterparts in this field.
