Welcome from Toowoomba, st13 will be very nice after the 650 (my last was a gsxf750). For long distance work many of us swear by our Russell day long seats, as I recon the stock seat is quite uncomfortable after an hour or two. Also worth doing some work on the forks (springs, oil, oil level, preload) if you weigh over 65kg. I am 85g and was using over 1/2 the fork travel just sitting on the bike!
St's are easy enough to work on once you have removed the plastics (see the Tupperware guide on the furum).
Have fun with your new beast :-)
