SB, this is predomenantly a naked bike/919 site, so the negative responses are to be expected. And thet's OK, everyone likes something different.
I have an 07 CBR600RR. It's a fine machine. I think it's every bit as comfy as the 919, but like I say, everybody's different. Mine has HeliBars on it, tho.
I like the power delivery of my 6. Revving a 6 isn't like revving a big bike, it has such a short stroke. I like spinning an engine and shifting gears.
The 6 doesn't do as well on gas, if that matters. The big downfall is the 6 isn't a whole lot of fun until you're doing way over the speed limit. It works for me because I know a lot of nearly deserted roads.
A good comprimise may be a 599. I really like mine.
