Theres a 98 yz 400 f for sale at a local dealers and im not very familiar with this bike. I think it was yamahas first attempt at 4 stroke engines. I was wondering what owners of this bike thought of it. Im guessing that its a little on the heavy side but im used to that, I own a 1999 TTR 250. I'm looking for something that could be brought to the track occasionaly and be ridden in trails most of the time. I have no problems handling power and riding all out. Im young and in good shape and I love a bike that'll kick the crap outta me by the end of the day as long as i'm haulin ass. So any thoughts on the machine by anyone who has driven one or better yet owned.
