Who makes Double Global Inc. engines?

Double Global Inc. engines were built by 2 different Chinese factories across 2025–2026: Chongqing Rato Technology Co., Ltd., Lifan. Which one built yours depends on the model year.

Will parts from another brand fit my Double Global 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.
