Kestrel Take

The workhorse standard — Honda's Foreman 520 is legendarily reliable, with a durable engine and Honda's tough drivetrain making it a favorite for hunting, farming, and trail work. It holds value strongly. Utility quads get worked in mud and water, so the airbox, radiator, bearings, and CV boots are the inspection. A well-kept, un-drowned Foreman is one of the most dependable quads you can buy; verify it wasn't a mud machine.
