Careful now. 'round these parts that's blasphemy to say you can do anything but ride circles around your lawn on a 900
I am VERY comfortable on my 900. I'll ride it anywhere. I wouldn't hesitate for a second to take it coast to coast if I had the time and the money. (That's the funny thing isn't it, you can have lots of money but no time, or lots of time but no money!). I don't disagree with people when they tell me the engine is 'buzzy', but, it doesn't bother me a bit. I have made a few changes for comfort though, like gel-gripped gloves to eliminate vibration in the grips (though there really isn't that much), a much comfier seat, and a tour pak and hard bags. BUT, all in all, I spent a lot less than a touring bike, get 50mpg consistently (up near 60 sometimes), and have a bike that is super reliable, easy to maintain, and easy to handle. I think the cool thing about the 900 is that a brand new rider can start out on it, then take it across the country!
I would like a GL1800 one day though. It's kind of high on my list. 3 riding buddies of mine ride them and the more I look at them, ride them, sit on them, the more I really like them. But, speaking of V-Twin vs Inline, I'm not too ashamed to admit that a part of me really likes the sound and personality of a V-Twin motorcycle. My V-Twin motorcycle feels to me like a muscle car, whereas the Goldwing feels like a really peppy Accord. I dunno, just can't get past the allure of a V-Twin!
