I think the nearest thing to a modern equivalent of the café racer is the street fighter. I don't think it's a tautology to call something in the style of a café racer if you don't think it's the genuine article. Busastars thinks his RD350 is café racer style but he doesn't call it a café racer.
Since the expression "cafe racer" refers to a motorcycle built in a certain style, then the phrase "cafe racer style bike" is, by definition, a tautology.
Whether you think it's the genuine article or not has nothing to do with it.
