Is this the right chain to replace with?

First link is to a NON O-Ring chain, you at least want an O-Ring chain, possibly an X-ring if your feeling spendy. The second link says it fits an 04/05 CBR1000RR :icon_confused: so not the one your after. If your after a chain you want a 520 O-Ring chain.
For my 2001 model I've just ordered a DID 520 X-Ring chain, 110 links to go with the stock 16/39 gearing. The original chain's given up the goat at 38k km :2guns:
My Chains and Sprockets (http://www.bbburma.net/Documents/GS500_Chains&Sprockets.txt) page is almost a year old, but maybe it will give you some more options.
