I have a set Mattracks for an RTV 1100 with only about 20 hours on them, they cost me $5,000 something (will take $2500), and are in execellant shape. They take too much power away from the machine here in western WY, 6200' in the valley floor. As soon as I get the !!00 fixed (stuck in reverse) it will be up for sale also (a 2006 a year old in Nov '08), but only to someone that lives at less than 4000' msl.
