NEW Shim's at 15,000km service,,,Is that right

I'm ready to do my next service at the 15k mark.had a chat to the service dude and he told me that maybe
I might need to change the shims on my SDR.
is this right already at 15k to do the shims,as my benelli tnt has 40,000k's on her and still don't have to do the shims.
seems a bit soon I think.maybe I'm wrong.....

they need to be checked and replaced if necessary.

It is correct they are checked at this service interval , mine didnt need any work , however they checked them......allegedly
