Clearly the previous owner was not a maintainer, possibly worth the effort to disassemble rear pulley assy., check internal bearings, guide pins, re-lube, etc., can't really picture it being ok, after seeing that carnage. Here's a PSA* diagram just for general info.
I'm sure whoever was driving it new something was wrong but drove it anyway.
Not sure what has happened, bike seemed to be running OK no major problems but clearly this one could not go back into service.
Clearly not a normal failure, but definitely a neglect failure, the rollers simply were worn beyond the minimum gap of ramp plate, that one was clearly worn more as seen in pic and simply slipped out of place, rollers do not wear evenly, especially when there's a lot of dust, etc,.(neglect). Love to see the variator inner pulley carnage :(

Here's a PSA* diagram of rear pulley assy., just for general info. do this at every belt change and you will be ok, the rear pulley is very neglected on scooters. * Public Service Announcement

Thanks for that ZRX. Clutch to my eyes looks OK.
The only way to truly check that rear pulley assy. is in good operating condition and properly, is to disassemble clean, inspect, lube internal components, not sure how one determines is serviceable otherwise, "Looks OK" from the outside does not reveal much, yes, the part of the clutch shoes that I can see looks ok, but I can also see a mark, were apparently a chisel and a hammer where used to remove/install clutch retaining nut :unsure: , if that's the case and based on what I already seen, in kind of shows some unorthodox mechanics worked on it :unsure: I would not hesitate to at least take a look at internal bearings and regrease. BTW a light scuffing on all pulley faces with green or red scotch-brite pad is always recommended when replacing the belt.
