Is 190km/h possible on Honda CBF500?

Well the truth is that I still don't know if my Honda can make 190km/h. Today I was in the mood for a quick run on the highway and I pushed it to 180km/h. Probably because of a small slope it didn't quite make it all the way :) and I didn't feel like pushing it for too long. I think I identifyed the source of the noise ... must be the chain. I cheked it out and it looks like all the grease is gone - again. I hope the service mechanics will have a solution on monday.
