Unbelievable track, put one on my 01 800 a few years ago and all my buddies want that track on their xp's. She climbs very well. Put in a bigger chain case to run bigger gears, then dropped and rolled it. Running 8 tooth extrovert drivers also. Had to trim the rails down. I run the track as loose as possible and it does slightly rub sometimes at the front top of the tunnel. That track is so much fun throwing down the himark with that old iron.
