Fresh bodywork and a relatively svelte, 5.3-gallon fuel tank replace the old bike’s so-called styling with a modern, functional look. Tough, fiber-reinforced, black body parts are allegedly easier to repair as well. A compact instrument cluster behind the reshaped, adjustable windscreen conveys more essential information—ambient air temperature and average fuel mileage displays are welcome additions. Anti-lock brakes are standard equipment, and Bosch’s latest 1.5-lb. ABS unit weighs less than half as much as its predecessor. Suzuki says those brakes stop a 472-lb. package: 13 lbs. lighter than the 2010 version. This 645cc V-twin is less than the 800-class version we were hoping for, but there’s more going on in there than you might think.
