I like to keep kind of current with what different sled manufactures are offering. What does Polaris have in 141 with a 2.52 pitch?
If you buy a 141 make sure it is not a yokohama track. They were over weight and not very durable. I put 5000kms on mine but it was all strickly mountain riding. I was starting to loose lugs but the track showed alot of stress type cracks along the kevlar belts. I ended up at 151" , but I never intended to use another 141. If you get a 144 it opens up alot more options of track style, and I would get a camoplast track.
