I bought one about 5 years ago for my MT Viper. It was one of the first flat top highrises. When I finnally got it, I was thinking WTF! This is a piece of crap. 5 Years later that seat looks excatly the same and I rode the hell out of that sled. Took a while to get, looks somewhat cheesy, but it is very light and seems to hold up extremely well. Now I have a new cat with the snocheck one. It is a little on the firm side but, seems like the same quality. If i had a new xp or Poo I would probably not bother as their seats are good height and shape from the factory. But the old style sleds and new Cats need one for sure.
