Ferrari bike In the 1970s, Kay Engineering crafted a racing bike, now said to be worth half a million dollars, with full factory backing to honor Enzo Ferrari. In the '80s, legendary motorcycle designer Arlen Nessi styled a one-off chopper on the Testator, while some guy named George crafted a pair of Ferrari-powered super bikes.
