I have a 08 m1000 and i noticed one of my rear wheels was chewed up a little bit (think a wrench fell in there when i was in the garage) anyways i was looking online and people were talking about getting a 2 wheel kit for the 08 and i only have 2 rear wheels on there now so im assuming that someone already did that to my sled ...just double checking that its not stock so i can try and figure out what wheel to buy ...btw im going sledding today! snow is still awesome up lolo pass (montana idaho border)
