| Hiya,
An SSie cant be THAT old so unless shes been ridden ALOT I'm quite surprised at this happening already.
I dont think there is any hard and fast rule about how many rings should be showing - rider weight (sorry) and if you have had a pillion etc will all effect the wear in suspension generally - so I believe its just a case of finding what is 'right' for your bike.
Could be time for a rebuild however, is everything else OK? No leaking fork seals - rear Shock ok and ride height / sag correct ??
All things to consider sadly.
