The classic style of motorcycles of the past just can’t be beaten for coolness. Now, there’s a way to tap into the coolness of retro style. The new KN-Kone motor combines the look of a knuckle, with the bullet-proof design and charging system of the 1970-’99 style alternator lower end. The KN-Kone motor features the S&S Super E carburetor and Super Stock® single fire ignition system.
