Summit X Expert, runs amazing tons of power it’s a wheelie machine which makes it a ton of fun to play with. I’ve only run ethanal free 91 octane. Mileage is 825 miles. It’s a clean machine ready to ride. I have the title in hand. Only reason for selling is becauase i bought a 2024 Skidoo lynx. I need this sled gone so I can pay off my new sled.
