Crazy pictures indeed.
Anybody know if you can feel or hear it clunking when that occurs, or is it spotted at some stage as damaged?
Some are instantly obvious; some not so much!

It depends on all sorts of things: how badly it's damaged the belt, ie. is it just a hole or a dirty great chunk of teeth gone; how big the rock/pebble/chip seal grit that did the damage is; where it's damaged the belt, on one side/edge or in the middle; did said pebble/chip seal grit get caught in the sprocket's teeth so that it's now ripping the belt in a new spot with every rotation (see Freddy's pic); did it damage a couple/few sprocket teeth as well; and the list goes on.... :dontknow:
But for most, as you may have noticed from the responses above, any belt damage you're most
likely to score (
IF that ever occurs!

)
won't usually mean you're stuck on the roadside - even Freddy's belt pictured, that was clearly 100% damaged & a throw-away, yet that happened somewhere in Oz, where the distances between places can be significant, yet it would've got him a fair way if not all the way home, and almost certainly would've let him ride to a place where he could at least seek help! :lecturef_smilie:
Sure, there'll be the few occurrences where the belt totally snaps just to prove the adage, but
MOST belt damage is relatively minor and doesn't stop the bike from riding on; the belts
ARE massively strong; and these belts are considered to be 'self healing' for minor holes, just so long as the sprocket/teeth haven't got a pebble jammed in them &/or the teeth haven't been torn/damaged so they'll continue to damage the belt!
Personally, I'm more concerned about
sprocket tooth damage than I really am about any
belt damage... but then, I only ride about 10,000 miles of dirt most years... :donyknow:
