He hits a rock at 3:21. You can see his right ski go airborn. The Skidoo almost hits the same rock with the left ski at 3:22. Same thing happened to me once. Hit a rock on far right side of trail that threw me all the way off to the left into a small tree. Was able to ride it home and a couple A-arms later was back in business.
I caught a boulder last year with my 2020 Indy and thank God the new sleds the control arms and anything attached to the engine cradle just tear right off! I was back on the snow in 24 hrs the older sleds you can do all kinds of bulkhead damage my buddies have ski Doo revs and they bend the bulkheads without hitting anything hard!!
Ouch, I was riding at night, went down in a ditch, and before I knew it, there was a culvert coming up to a driveway I tried to steer away. The edge of the culvert, caught the plastic ski, bent everything the arms bent the post that came out from the frame there was no easy way to bend it back, replaced the parts that I could and just had to live with the vent frame post still drove OK afterwards you didn't notice it but it had a lean to one side if you sided it from the rear was a terrible day day second time on a new snowmobile arctic cat fire cat 2005
