Power for the Vulcan 800 Drifter comes from an 805cc V-twin SOHC four-stroke engine with a single-pin crankshaft for a classic V-twin rumble and 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 and allow more precise cam timing, while a spin-on oil filter helps make maintenance a quick and easy job.

The Drifter's 36mm carburetor features the Kawasaki Throttle Responsive Ignition Control (K-TRIC) throttle position censor, which is connected to the digitally mapped ignition system. K-TRIC varies ignition timing according to throttle position and engine rpm so that the ignition compensates for differing engine loads. The result is crisp throttle response and better fuel efficiency.

At the rear of the single backbone, double-cradle frame is a sleek, triangulated steel swingarm and Kawasaki UNI-TRAK® linkage rear suspension system, which provide a smooth ride while maintaining the retro look of a hard tail cruiser. Front and rear disc brakes provide plenty of stopping power.

For comfort, the Drifter's specially contoured solo saddle is nice and low, allowing the rider to comfortably plant both feet on the ground at stops. Wide floorboards allow for a relaxed sitting position, a heel-toe shifter makes changing gears in the five-speed transmission a snap, and self-canceling turn signals add to rider convenience.
