I have 7500 km on it, with 450 hours. I ride mountainous terrain as well as do flat land utility usage at the cottage, and it’s been solid as a rock every step of the way. I’ve never had trouble climbing hills, going through bogs, etc. The occasional time I get water in the transmission case and the belt slips, but I’ve just drained that, let it dry and it's fine. Never had a break down on the trails. Its completely stock, no mods, although the next set of tires for it I might go to the ITP Mud Lites. The IRS is golden to have in the rocky terrain. I've crossed rivers with it, submerged it in mud holes and had to swim it out. Starts every time.

I live on a lake and use this to put my boat lift and dock in and out of the water. Twice I've dropped the quad through the ice and submerged it, and drove it out. Drain everything, and its fine. Never had to replace anything on it. Only wear part I've replaced so far is the brakes once, which was easy enough I replaced them myself. I use it in the winter as well, just let it warm up for 10 minutes before I ride it, and it performs just the same in the summer. I don't do much for winterizing as it's used usually every 3 weeks at minimum. Little bit of fuel stabilizer if I don’t ride it for a month. I do regular service (oil changes, etc.) and that’s it. I was surprised that it was actually quite fuel efficient despite being a 660cc. A tank of gas (12L approx without going into reserve) lasts me 8 hours of riding. I get tired before the quad runs out of gas! I'm looking forward to the next 7500 km!
