Harley-Davidson is releasing it's first new motorcycle in over 13 years with the release of of the Street line of motorcycles. They will be released in 500 and 750 and feature an all new liquid-cooled Revolution X powertrains. This introduction is another part of the Project Rushmore line of upgrades which was released last August. "These are the newest motorcycles to join our Dark Custom lineup, which helped make us the number-one selling brand to young adults in the U.S. for the past five years," said Matt Levatich, President and Chief Operating Officer, Harley-Davidson Motor Company. "Both the Street 750 and Street 500 were designed with thousands of hours of input from young adults in cities around the world. This input guided both the attitude and capabilities of these motorcycles. They are proof that being customer-led continues to be a core driver of our product development process." The Street 750 and Street 50 features the new Revolution X engine, designed to match the demands of stop-and-go traffic with nimble agility, while delivering instant throttle response to escape city gridlock. The Revolution X engine will be housed in a new, narrow and lean chassis built for agility, with a super-low seat height, new suspension and broad handlebar sweep that provides confidence and maneuverability when managing tight turns and fast moves. Both signature Dark Custom motorcycles feature a premium, minimalist style that serves as a blank canvas for riders to customize. "These new bikes are leaner, yet still have a mean streak - they're the real deal, made of real steel." said Mark-Hans Richer, Senior Vice President and Chief Marketing Officer, Harley-Davidson Motor Company. "They're designed to handle the abuses of urban environments and provide authentic opportunities to customize." The Harley-Davidson Street 750 and Street 500 will be rolling into dealerships in select markets starting in 2014. More information is available at www.h-d.com/street.
