I think it's a cx650e but he refers to it as a cx500e.
Watch more than the first 30 seconds of the video. He says that it is a 1986 cx500e. I don't think they made CX500 e's in 1986 or even tag them as such. Plus the valve covers resemble a 650 to me. I don't know if there's huge differences other than valve covers and carbs that can distinguish a 500 E from a 650e especially one that has been modified but calling it a 1986 should have declared it a CX 650e. The fact that he shows a picture of a white cx500e right before he shows the cafe version doesn't mean that they started with that particular white bike. He shows lots of standard CX 500 E photos shortly before that.It's an early twin shock 500. Single spine frame.
For the first 30 seconds or more he is showing other CX cafes that he has done video reports on. And then he says but there's one that he has not done yet and he goes into the E-Series.At 3.49 we see a bare euro type frame. But the bike starts out with a single spar frame at the beginning.
Unless that bike was just his inspiration.
It is computer generated, and you will occasionally hear it on other unrelated you tube videos. This guy is from Portugal, so his English is probably not as good as he would like for presenting his videos. He tried recently for one video to use a human professional presenter, which was overwhelmingly rejected by his viewers. So his channel will always be associated with this AI english accent.It kind of grew on me but I admit the combination of the accent and the choppiness of the computer generation is sometimes annoying.
