Chongqing CQ 1 10-9E Translunar Engine was built. In fact, Chongqing brand motorcycle is a sub-brand under construction, and it is only different from similar models under construction in trademark, but there is no difference in other aspects. The engine of this car is the same as the Yamaha F8 or E8, but the Yamaha brand is marked on the Yamaha model. However, because Jianshe and Chongqing are not joint venture brands, Yamaha brand can't be used, and only the trademark of Jianshe or Chongqing can be used.
