No matter which platform Kawasaki puts the 650 cubic two-cylinder in, the result is always a great motorbike! Even though the engine is unusually rev-happy for a cruiser, it results in a cruiser that actually qualifies as a sports cruiser when paired with the sporty chassis set-up. The only brake is the limited lean angle clearance, but this will not deter lovers of hearty footrest grinding. With such a good bike, we hope that Kawasaki will follow suit - after all, the Vulcan S has been with us almost unchanged since 2015.
