Originally cafe racers were based primarily on British motorcycle marques. They were lean, stripped-back bikes built to go fast. Owners would remove any unnecessary components, fit parts designed for the race track and even swap engines and frames in the hunt for more power and improved performance.
Rusty, other than the Dustall style exhaust pipes, my Norton is 100% stock.
Between the stainless, chrome and polished aluminum, it's just as it was.
