A true middleweight naked sportbike for a broad range of riders, the Z650RS tempts the eye with the timeless beauty of a retro sport. Distinguishing the Z650RS from the larger displacement Z900RS is a slimmer tank and a shorter, more compact tail—all contributing to light handling and an approachable nature. Experience modern responsive power and retro styling that’s perfect for everyday riding on the Z650RS.
