Harley-Davidson introduced its first official trike in years earlier in 2008 and now looks to flip things around a bit with a new reverse-trike that leans into corners. Rumors indicate that the huge American Motor Company will bring the corner carving trike in concept form to a motorcycle show set to take place next month in Cologne, Germany. If that debut indeed takes place, the machine is likely to be powered by the liquid-cooled Revolution V-Twin engine from the Rod series as opposed to the 45-degree air-cooled mill powering most of its bikes. We've known that the company has been working on this design for the past few years, filing patent drawings way back in 2006. The market is definitely ready for it now that Piaggio and Can Am have toed the waters. We look forward to seeing just how accurate these rumors prove to be next month. Thanks for the tip, Moose!
