I hear similar sentiments to that from lots of modern "Cafe" builders, but basically, it's all bullschitt. True Cafe Racer types wouldn't urinate on a Japanese bike, a real Cafe Racer is an old Triumph, Norton or BSA twin, not a Honda 4, or anything else that wasn't even around during the Cafe Racer's heyday.
It should be remembered that the whole Cafe "fashion", mods, rockers, whatever, was only a very short lived thing, and was dead long before the Honda SOHC4's arrived. I was in England for a few months in 1974, and by then, Choppers were all the rage, and all the old "Cafe Racers" had been "re-customised" by another generation, with tasteful mods like extended forks, ape hangers and sissy bars.
Cafe Racers were dead by then, because you could buy super fast, super reliable big Jap bikes by then, and their riders were a little more refined than their greasy haired predecessors. Cheers, Terry.
