2020 Suzuki DR-Z400S — Should You Buy One?
Typical asking price: $5,000–$7,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
The legendary do-it-all dual-sport — decades-old design, carbureted, simple, and nearly unkillable. It's the default recommendation for a first real dual-sport and holds value accordingly. The carbureted hot-start quirk, stator, and hard-ride wear are the only real check points.
