The pulse of the Vulcan 800 Classic comes from its rubber-mounted, 805cc, V-twin engine, which features a single-pin crankshaft and a gear-driven balancer to reduce vibration. Finned cylinders and four-valve heads are liquid cooled for optimum thermal control. Concealed automatic cam chain tensioners preserve the engine's clean lines, while simultaneously allowing maintenance-free, precise cam timing. A spin-on oil filter also helps keep maintenance at a minimum.
A 36mm Keihin carburetor equipped with an accelerator pump gives the Vulcan 800 Classic its quick throttle response. To take advantage of the engine's broad torque curve, the five-speed transmission enhances the strong acceleration and creates a relaxed engine pace at highway speeds. The transmission also features Kawasaki's exclusive Positive Neutral Finder, which simplifies finding neutral while at a standstill.
