Typical asking price: $8,500–$13,000. There are 2 high-severity known issues you need to know before handing over a check.
Kestrel Take
A light, capable deep-snow mountain sled with the Patriot 850 — combining the 850's early-update homework with the hardest use pattern any sled sees. Verify the engine and belt-drive updates plus the top-end history, then inspect for the mountain abuse these inevitably take.
What we checked
Not checked against public records
Snowmobiles fall to the Consumer Product Safety Commission rather than NHTSA. It publishes recalls but no owner-complaint record, and only a minority of campaigns name a model year we can match with confidence. 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.
