First - newbies posting about huge motorcycles and asking, "Is this too big to start with?"
Cripe.
YES! It is! You already KNOW it is too big. You're just looking for some testosterone-filled nimrods to convince you that you're man enough to handle it. And they will. The macho dorks will support your stupidity from here to eternity.
Stop it. You're already smart enough to know it's too much, or you wouldn't be asking in the first place. Have the self-respect to acknowledge your inability to handle it right now, and get something more manageable.
No one ever asks, "Is the Ninja 250 too big?" or "Is a Honda Rebel too powerful?" Ride one. You'll find out that small motorcycles are already WAY more than you can handle as a newbie. Okay, toughguy?
Second rant: Respect the bike.

Okay. Done ranting. Back to your scheduled websurfing.....
