Its the just in case situation. The belt will never shred itself in the woods and leave you stranded, I have never heard of one do that before. It may slip but not break. If it is tightned to the proper spec you will have no problems. I know my belt is starting to get loose on my V-Force and I will need to remove a shim in the next 2 months or so. If you go on a big 2 week ride with friends and family then make sure before you leave the belt is in spec and don't worry about it. The motor does not rev high enough to shread it, like a sled can.
