I unfortunately lost the track out of my '02 800 XC this past weekend. I was planning on getting a new track for next season, but I dont have a choise now. I curently run the flatlands of Michigan trail riding with the occasional deep powder ride 1 or 2 times a year. I am thinking about stretching it to a 136". Is it worth it for the money for a flatlander? Also, I was trying to decide between a 1.25" and a 1.375". Is it worth the money to go to the 1.375" over the 1.25". What is everyones experience?
