Looking at possibly picking up a used YZF450, $3600 is the asking price. The bike is a ex race bike and has been taken care of by a factory dealership. The bike looks well maintained. I have approximatelely 17+ years of riding experience on the street but have not been off road for quite some time. I was thinking of easing back into this with a 230 or a 250 but I stumbled onto this 450. I am 6' 4 and weigh 200 pounds. All I was searching for was a bike to plug along the trails with my kids on. Will this be the wrong bike to do this with? I understand that I will have a blast and be able to pull some torque wheelies with this bike, which I remember the good old days were like on a friends early YZ400. I loved that bike. I had posted in previous forums asking about the 230's and 250's, some said go for a bigger bike. But should I be going this big? Lastly, is there anything that I should be looking for on this bike in terms of wear being an ex race bike? Like I said, it looks pretty solid and complete, just want to make sure I'm not missing something. I was also looking for something with electric start being that I was going to be riding the trails with the kids, but the trade off of power will be worth it. Are the 450's a mule to start? Any information on this would be helpful. Thanks!
