2013 Kawasaki Vulcan 900 Custom, The Vulcan® 900 Custom has a 903cc liquid-cooled V-twin engine, stylish cast wheels, forward-mounted foot controls for a laid-back riding position, and a 5.3-gallon fuel tank. It s easy to imagine the Vulcan 900 Custom s competition comforting themselves with words to that effect, but one ride is all it takes to discover this cruiser has far more than just great looks on its side. This is one machine that manages to be both easy to ride and also powerful enough to more than hold its own against much larger cruisers. Of course, its stunning good looks, expert engineering and long-term dependability certainly don t hurt!
