My bike is a 2008 model, the models that experience the problem.....
Yet, I have never suffered and I have the original Rectifier Regulator.
I always maintained that this was not a failure of component, but a failure during PDI (Pre Delivery Inspection) in that the supplying dealer did not check all the connectors to ensure they were correct. The plug assembly is more fragile and susceptible to moisture ingress than the normal connectors, and so when it isn't connected correctly, water gets in leading to overheating of the connector, and failure.
There is nothing wrong with taking precautions and replacing the reg/rec assembly as per StoicBlokes post, in fact if it removes any concern then do it. Or you could ensure the connector assembly is correctly fitted together (a double click is the norm when pushing them together, but not always) with a little electrically safe grease around the weather surfaces during assembly, and a coating afterwards.
Mine has the contacts greased, and it's been good since May 2008. Some haven't been so lucky though.
