2012 KAWASAKI NINJA 650R / EX650, All-new Chassis, Bodywork, and Improved Power Delivery Make the Best Mid-sized Sportbike Even Better They're known as sweet spot motorcycles: streetbikes so balanced, user-friendly and all-around capable that they stand well above their two-wheeled counterparts, forging lasting reputations as exciting, practical and stylish machines. There aren't many such overachievers in today's narrowly focused two-wheeled world. Since its debut back in 2006, the multi-talented Ninja 650R has been a bona fide member of this elite group, winning accolades from owners and media alike. But for 2012, the massively reworked Ninja 650 is better than ever.
