2021 Kawasaki Mule SX — Should You Buy One?

Typical asking price: $6,500–$10,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A simple, tough, no-nonsense work mule — a small gas engine, a basic CVT, and a reputation for just working around a property. It's slow and basic by design. As an affordable, durable chore machine it's very hard to hurt. Check the belt and general neglect.
