We all know chains and sprockets wear together.

How about drive belts? Barring anything special, what's the lifespan of our drive pulleys?

Indefinatly, the belt won't wear the pulley within reason. I'd guess it's good for at least 200,000 miles.

The sprockets should last the life of the bike.

I know a guy who had to replace the front sprocket at around 70k miles - the compensator inside went bad. It didn't wear out the pulley as far as I know.

As far as chain/sprocket wear vs belt/pulley wear: Chains & sprockets are both metal. Belts are rubber/fiber, and pulleys are metal. I don't think it's quite the same... : )

my s1 has 94k miles the rear pully was soft aluminum with no coating. At 70,000 miles I put an after market one on. the front still looks good.

the 1125 pullys seem to be coated so they might last even longer.
