I replaced my track on my 02 700xcsp and the speedo side bearing was still good. I may change it for good measure next year as its not a hard job at all. My question is because the bearing is quite expensive through polaris are there other suppliers of this bearing? Also i noticed that the bearing has holes in the outside of the race for greasing. Why couldnt you just buy a shelf bearing with the same dimensions and pull the inner seal and grease it that way??
