Hi, this is my first post here, and I have been doing a bit of reading about different bikes. I found a '00 YZ426 for $1700, and was wondering if this is too much for me to handle as a first bike? I am 5'9, 190 lbs, mostly muscle, not a fatass. Will I be fine on this bike, and not kill myself with the power it makes? I think I should be fine, but I want a few opinions.
