Hey Rich - post #6 is FULL of consistantly referred to info on these bikes.
I've never owned one (yet) but they are my fav bike in Honda's long lineup.
Those that own them, have had their brain picked by me, and, like I said, post #6 is spot on - although, I've heard from other owners that the front brakes are the weak point on an RC51, contradicting post 6's review. In any event, the bike will come to a stop regardless.
As for gas leaks, we know you have experience with that

.
Here's a nice 2003 RC51 for investment purposes, barely broken in, with < 1,900kms:

Please buy it, before I go and do something stupid
