Who makes Zxmco Usa, Inc. engines?

Zxmco Usa, Inc. engines were built by 3 different Chinese factories across 2008–2009: Jiangsu Zhongxing Motorcycle Co., Ltd., Jiangsu Zhongzing Motorcycle Co., Ltd., Zhejiang Summit Huawin Motorcycle Co., Ltd.. Which one built yours depends on the model year.

Will parts from another brand fit my Zxmco Usa, Inc.?

A shared factory and engine size makes another brand a strong candidate, but it does not prove the part numbers match. These machines are assembled from multiple component suppliers, so measure the part you have before ordering a replacement.
