Why do you want a high cc bike? Its a slippery slope to disaster IMO. You redline in first gear and your OVER the speed limit. You think you can use all 1000cc on the hwy or mts? Good luck with that. You'll be one of those on the side of the road looking stupid, with harly guys laughing as they pass. Trust me, its the worst feeling. Not to mention the 40hp motards that can pass you in a turn. Even after riding my 600 through deals gap, 129, 180, and 60; 10-20 times, I rather have a 500. But hey, its your life and I wont be making the decision. I too became a statistic and bought a sports bike as my first.

As to the original question. Hondas are the most expensive out of the 3 but good reliable bikes. Yamaha is also more expensive than a Suzuki. Suzuki's have been number 1 in every class (600, 750, 1000) until this year (if i recall correctly) when the 06 R6's came out. Suzuki is cheap, I bought a brand new 2005 gsxr 600 for $7,000 out the door, where my friend bought a 2005 CBR600RR USED with 4500 miles on it for $7500.

These bikes are so fairly similar in performance so it all comes down to personal preference. Go to a dealer and sit on the bikes and see how you like them. As for me I'm a Suzuki guy, but I am lovin the 06 R6's..
