In my opinion,
yes it's comfortable. Currently in the garage is the 02 Hayabusa, an 02 Harley Softail, and an 03 Goldwing (well, my wife's Aprilia and a 76 chop in pieces but they don't count
). I've ridden all three on trips.
Of the three, the Goldwing is the
worst. My back was bothering me after an hour and killing me at the end of a 300 mile day (997 miles in three days). The Harley's much better. The longest trip was 7000 miles in just under two weeks. I have a Corbin seat with backrests and I've extended the forward controls to accomodate my longer legs.
But the 'busa's the best of the three. Less than a week after I bought it, I went on a 5 day, 3000 mile ride which included 1035 miles for my first Iron Butt. This past April I went on a 6000 mile ride which included two days visiting family and friends, half day in Northern Arkansas and a day riding in the Deal's Gap area. I bought it with 3900 miles on it July of last year and it's up to 22189 miles now. I'm getting ready for three weeks of short and long distance rides.
It has Heli-bars. I added a Second Look tank bra for personal stability (I can grip the tank with my knees without slipping off), Pro-tekk pegs because of my longer legs, and mirror extenders (purchased from a member here; which work great BTW!).
When I tour, I have a Joe Rocket magnetic tank bag which I strap to the tank pivot. This way I can lay on the bag without it moving. I use the Tourmaster Cortech sport saddlebags and the Oxford sport tailbag.

over here for my touring pages. Especially
this page which documents my ride preparation and includes an inventory of what I generally take (slightly different if I'm camping too).
If you're interested in touring on the bike (and no slight intended to the fine folks here), you might also check out the sport touring site. Currently Gixster is somewhere in California after being in Las Vegas a couple of days ago.
