Professional competition generally refers to MOTOGP and other competitions, and one-piece leather clothing should be worn. At present, MOTOGP contestants generally wear Dennis and A-star, which are customized by motorcycle manufacturers for drivers. They are equipped with electronic airbags, and they are not injured when they fall for more than ten or twenty meters, and there are tens of thousands of them. There are also customized motorcycle leather garments made by domestic brands. In addition to the absence of electronic airbags, the performance is also at the track level, which is similar to the price of J-RACiNG for six or seven thousand.
