I have been snowmobiling since 1964. I am we'll past the 100,000 mile mark on snowmobiles, and have only been towed back 3 times. #1; 1991 Polaris Indy 500 SP, broken crank. #2; 2005 Yamaha RX-1, hole in front heat exchanger. #3; 2007 Yamaha Rage GT, hole in front heat exchanger. Had many small things break in numerous sleds but was always able to limp them home.
