My 2017 FX (purchased new in 2019) has about 14,000 miles.  I had the chain kit on it for about a year and then put the belt back on when the chain was worn out.  I heard some unusual noise, kind of clicking like, particularly when regen would kick in for a week or 2.  I checked belt tension and watched the wheel and belt with the bike on the track stand and the motor running.  Unfortunatley, I didn't see anything.  It failed on the way home the other day and I found that all the splines in the pulley were nearly gone.  You might be able to see it in the photo.  The shaft on the motor has a little damage but I think a new pulley will still work.  I was at the dealer today to order it for $101+ and was told it may take 2 or 3 weeks.

Just wondered if anyone else has had this problem.

That's a very surprising failure mode, I've not even heard of the torquier R models doing that. Generally it's the belt that is the weak link. Interesting that you have the 20t and not the 18t pulley (which means even less load on it), I assumed the 6.5 would use the smaller pulley like the 7.2 models do. You could change your order and get a little bump in torque, presumably you have the dongle to adjust the speedo to the different ratio and you had the chain kit or you have the dealer do it.
