I'm looking at buying a CTR **** for my S2K, but was wondering how people can tell if it's authentic or not? My searching didn't lead to much but said something about a stepped lip at the base? Which is what this one has I believe. It is weighted. Any other tips for telling if this is an authentic **** or not? The price is $55.

Here is a couple pics of the **** for sale:

 

I have one for sale..I ordered it from procivic.com and it came in the Honda box with the part number..I do not think I have the box any more tho
