Chongqing Yinxiang Motorcycle (GROUP) CO., LTD was founded in 1997. It is a large industrial group with 12 subsidiaries. One of their areas is the production of motorcycles and gasoline engines.
Since 2002, the Yinxiang Group has become a joint venture with Hyosung motors & machine Inc Korea (Manuals page), as Chongqing Hyosung Motorcycle Corporation Limited, setting up the import of new production technology from Korea.
Since 2007, Yinxiang has decided to occupy a niche in the field of production of high-quality fuel-efficient engines. The logical development of this direction was the creation of popular motors, which are installed in the chassis of every third pitbike.
