2021 Ski-Doo Grand Touring 900 ACE — Should You Buy One?
Typical asking price: $9,500–$14,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A comfortable two-up touring sled with the smooth, efficient, and famously reliable 900 ACE four-stroke — the low-maintenance, long-life engine choice. Ideal for couples and long trail miles. Inspect the belt, track, and heated accessories, and buy on service history.
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.
