The modern concept of the cafe racer has strongly evolved since it was first created in 1950s in London. The first cafe racers were simply production motorcycles with more powerful engines. They were usually equipped with clip-ons and knee-indents in the fuel tank. All superfluous parts were removed to make the bike lighter (fenders, chain guards, side covers, and sometimes even headlights).
A modern cafe racer is a vague concept. They refused from the original concept, but still try to follow the usual look.
