Will parts from another brand fit my Cobra Scooters?

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.

What the Cobra Scooters filings say about the engines

Every Cobra Scooters filing on record is carburetted — 12 certificate rows, 2009 to 2013, and not one fuel-injected engine among them.

2 of the 12 filings are 50-state (California-legal); the other 10 were 49-state only.

Rated power across the range runs from 2 kW to 6.5 kW (about 3 to 9 hp).

The vehicle builders named are Ghangzhou Panyu Huanan Motors Group Co., Guangzhou Panyu Huanan Motors Group Co. and Ningbo Longjia Motorcycle Co.,LTD — the chassis and the engine do not always share a source.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
