2018 Harley-Davidson Street Glide Special: A blacked-out Milwaukee-Eight® 107 engine sits at the heart of dark finishes that flow from headlight to exhaust. A new 19-inch Talon front wheel and 18-inch rear wheel. Stretched saddlebags that accentuate the long, low profile of the bike. Blacked-out front forks, handlebars, tank console and exhaust for an aggressive, modern look. And a premium audio system featuring Stage I BOOM!™ speakers.
