My first bike was my '01 CBR600 F4i. It's the same one I ride today.
I started riding only a year ago (hence my username) and I would tend to say that it was a dumb decision that I didn't start on a smaller bike first.
I had virtually no experience before buying my bike, besides riding a couple of dirt bikes that my friends owned.
Within the first month, I had a bad spill and I was in the hospital for a week. Since then, I've dropped it several times, and it hurts to ride on it for long periods of time, because of the metal rod in my left leg from the accident.
Looking back, I would have gotten a CHEAPER, less powerful bike to start with. I'm just now starting to feel a little confidence on it, but that's assuming it will even start for me. I'm still trying to repair everything on it from the wreck.
Yep, bad idea!
I know just enough to be dangerous!
