about how long do they normally last?

(fwiw, i got a xbones)

 

from all I read and seen 100k or more is not unusual..

 

Depends on how it's adjusted and how you ride. Worst case would be the next time you dump the clutch or it may go 100k with normal driving. Once the hp goes up, life goes down. No real definate figure on these things.

Go chain, a nice 530 o ring.....

 

As others have said, stock bike, easy riding, belt guards in-place, no stones, adjust to spec. etc. should be good for 80k/100K miles. Up the HP and TQ, twist the throttle harder, dump the clutch, do burn outs, remove your belt guards, ride on dirt roads regularly, etc. and you could snap it tomorrow.

 

My original belt lasted 115,000 miles.

 

My buddy spanked his in less than 5000 miles on his stock night train. I think they should last longer than that though!!LOL

 

from what i heard it is damaged before worn out from rocks
