I had 3 XP 800's last year. About 3000 combined miles. The only problem was the hand grips heaters. Roasted a lot of belts until the new 377 came out and then never lost a belt the rest of the year. Everyone on here likes to bash the new sleds. I ride as hard as anyone and this sled held up awesome. I was actually surprised how well it held to together with all the tree riding and bumping I do. Knocked a lot of trees and never bent anything. I've owned about every sled made in the last 6 years and this is as well built as any of them and its lite as sheit.
