"Any color as long as it's black." Not surprisingly, it was in the psychedelic seventies when motorcycle manufacturers first broke with the tradition of black-painted frames. First came BSA's "dove grey," intended, it's said, to reprise the company's titanium-tubed, motocross bike frames. Then came Ducati's teal-framed silver 750SS. But perhaps the most successful color combo was Laverda's pairing of the company's racing orange with the sleek silver tubes of its mighty muscle bike, the Jota.
