Seriously, it is an apples and oranges comparison pretty much. Neither is very comfortable but the R6 probably has the nod as being a little more comfortable. If you ride a lot of tight twisty roads then either is a blast. If you like high speed sweepers and the roar of a V-twin then the RC is the one to go with. The RC-51 will hold its value better than just about anything right now. The blue book value for the '00 RC-51 is greater than the MSRP was. Go figure. I haven't seen the blue book myself but was told that it said that. The RC is quite a bit more than the R6 though.
