I usually advise people who ask me to check out the bike mags for a year, or at least for several months. I specifically recommend CycleWorld and Motorcyclist.
The simple fact is, when you're first shopping for a bike, you may not know what all is out there. There may be some feautres you later hear about and wish you had, but which are not available on your bike (or were, and you didn't order a bike with them, and they can't be added on).
Additionally, you might want to take in a show. I fell in love with Moto Guzzis one year. I needed to move up to a bigger bike, and loved everything about the bike. I researched them, asked around, etc.
Then I got to the bike show in Seattle. Sat on one and hated it instantly. The ergos on it were ridiculous. I'm 6'3" and I could barely touch the ground with my toes. The heel-toe shifter seemed to be about 5" apart...bit of a problem if you wear a size 14 shoe, like I do. The hand grips were tiny, etc.
I nearly fell in love with a Triumph Legend, although I would have had to change the seat and handlebars to accomodate my dimensions and be able to ride two up comfortably. Then Mrs. Pacman spotted a Vulcan 1500 on the way out the door. Shaft drive, water-cooled, and fit me perfectly. Stock seat was (and still is) all-day comfortable, etc. Sticker price was $7999, about half of what Harleys were running.
I went home and began researching the bike. I opted for a 1998 model as I liked the colors, the 99 colors were blah and my research showed me the 1997 model the dealer tried to sell me had problems with at least one gear.
I've had the bike over 10 years. I still love it, I could give a **** whether Harley guys consider it a "real bike" or not, and I've managed to customize it quite nicely. My wife and I both fit on it comfortably, and with custom paint, pipes, bags, airhorn, etc., I'd bet maybe 3% of the population at most could identify it from 50 feet away or more.
Oh yeah...it also sounds great, makes more power than I'll ever need, and should outlive me. 10 years and change, and not a drop of oil appearing on the garage floor. Ask around about how many owners of air-cooled bikes can say that.
One last thing...if you're serious about getting a bike, as soon as you can, take the safety course. It will likely save your life some day. It's saved mine a few times.
