2020 Kawasaki Vulcan S — Should You Buy One?

Typical asking price: $5,500–$7,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A modern, approachable cruiser that breaks from the heavy V-twin formula — a light, liquid-cooled parallel-twin (shared with the Ninja 650) that's easy to ride and genuinely reliable. A great first cruiser. Drop damage and routine maintenance are the only real checks. Low risk.
