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 exceptionally durable. 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.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
