I second the feelings about just being careful and getting whatever bike you want. A STUPID FOOL is going to get in trouble on ANY bike. A good, responsible driver will be fine on any bike The size/weight/displacement/HP/whatever is such a minor factor. Starting on a small bike to save you from yourself? No. A large bike is no harder to handle really than a small one. --Actually, it's the other way around, in most cases. ANY bike of any size is going to take some adjustment period...getting used to the way it feels, handles, shifts, etc. During this period, you should be careful. VERRRRRY careful on ANY bike. --But adjusting to a larger, more powerful bike is no more dangerous than with a small one, unless you ARE being reckless and stupid. My advice: Get the bike you want. DO NOT get a bike too small for you, because you WILL regret it later. Be careful. Be careful.
I started with a honda express scooter. Moved up to a 125 dual sport. When I wet to college, my dad bought a GL1200 (Goldwing.) I rode it more than him. Shortly after, I bought a Suzuki GS550L. Too weak, that bike. FAR too weak. I was never satisfied, though I loved the bike dearly. I was lusting after my friend's Yamaha XS1100 Special. THen my dad traded for a brand new Goldwing GL1500. Good Lord. Rode it more than him (until he drove it to the FL keys.) THEN.... I finally talked my friend into selling me the 11 Special. No looking back. I tell you... If I had started with this bike, I would have been a happy man. --And still alive, yes. --Because, NEVER, on ANY of the great bikes I have had the privelege to ride regularly, have I acted like a fool on one. (Well, there was that one time, in a wide open parking lot, but....ANYWAY.) Get what you want. You don't want to be stuck with a too small, underpowered bike.
Now, when I say underpowered, I don't mean "a bike that can't get you to 100 MPH quick enough" or "a bike that doesn't have the kind of top speed you can be proud of." No, no. I mean this: When I am on my XS1100, fully loaded, with my wife on the back, also fully loaded, and I start moving....the bike goes. Happily. There is no over-revving trying to get up enough HP to move us. When I want to pass, I can do so without changing gears. When I want to turn onto a new road, I can do that in 3rd gear without lugging my bike. When I DO want a little exciting kick int he pants, the bike is perfectly willing to do so at all times. A little torque and HP goes a LOOOONG way in just making your everyday ride feel nice and smooth. You don't want to have to push your bike just to do the mundane things like starting at a stoplight or turning. And, sure, any bike HAS the power to start and turn. But if you get an underpowered bike, and then you ride one that has a little to spare, you WILL see what I mean, and you will look at your bike in a wholly different way. You'll never be satisfied again.
Just my 2 cents.
