2021 Kawasaki STX 160 — Should You Buy One?

Typical asking price: $8,500–$12,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A value-priced three-seat runabout with a naturally aspirated 1498cc four-stroke — no supercharger to rebuild, which makes it one of the lower-maintenance PWCs you can buy. A sensible family ski. Check the wear ring, impeller, and salt-water history.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Boats and personal watercraft are not in NHTSA’s database — that is the Coast Guard, which publishes recalls but no owner-complaint record. 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.
