this reminds me of the companies that have claimed to be the "manufacturer" of an electric motorcycle but are in fact importing a knocked down kit of electric motorcycle parts from an alibaba vendor in china.
I mean, if they make the frame themselves, I don't see the issue. It's like saying that the the first Buells weren't made by Buell because they had a Harley engine and Ohlins suspension.
most of them import the frame too, the difference is on the decals and maybe some plastic body pieces only
