Completely sheared all teeth from belt

[TapioK]

Here is a photo of an original pulley I wore out a few years ago. The belt was fine and on the bike when I got rid of it at about 75,000 miles. I had an oil seep that plagued me for most of a season. The belt was often subject to oil, and I always suspected the pulley wear was related to abrasion from sand and dirt sticking to the oil on the belt.
The teeth were really sharp and you can see where they wore out.View attachment 68805

Yep, mine was OK when I left for Daytona, about 500 miles later in Mind .... sand, water, salt and a little oil to perfect the mixture... Surprisingly the belt was still somewhat fine but I didn’t dare to ride the bike back home from Miami but ordered and replaced the pulley there. I still, a several thousand miles later, have the same belt

Damn, Tapio—that pulley would cut your fingers!!
My photo was from January 2016, so the bike would have been at about 50-55,000 miles at that time. Again, I think the oil coating on the belt would have attracted grit that accelerated wear on the aluminum pulley. Again, like yours, the belt was fine. Chrome plated too.
I was thinking that if the belt lost a rib or two, the rest would start to slip and the impact would tend to shave more and more of the ribs off until you have what Jwooky experienced. Sven would say ‘click....click....click....WHAM!’
Or maybe it was a flawed belt.

Agree the rear pulley is very worn. Not sure which came first. I already ordered a new one from Derrick/Donna. The front is not showing any signs of wear so I dont see any reason to change it

The exhaust does not blow on pulley. Its way offset form the top view.

I generally keep the belt on the tight side, and ensure it tracks centered in both directions.

I did have a trans leak a few years back for a minute, cant recall but it may have got some on belt.

Cant seem to find any info on belt as far as a major advantage. I think I will go with the goodyear.

Still have never heard of a belt losing all its teeth.

I saw it happen on my wife's 2011 Harley Heritage. Like you I just replaced the belt and rear pulley. I hung the worn pulley on the wall beside my lift as a reminder to keep an eye on the belt and pulley.

This is far from new, has many miles on it, but this is what a pulley should look like.
