Harley-Davidson will release their Street 500 motorcycle in 2015. The bike will feature an all new Revolution X V-Twin engine that is specifically designed for urban riding. It\u2019s liquid cooled to maintain peak performance no matter how high the mercury climbs. The single overhead cam and smooth shifting 6 speed transmission relates to one thing, instant response. The chassis is lean and narrow and the seat super low for easy handling. The premium brakes and skinny front tire assist for tight turns and quick moves.
