ok. I am ready to get a new bike. I have an 01 YZ250f now. Great bike, nice power. I am sticking with Yam but am unsure if I should get the 250F or the 450F. I ride 40% track 60% woods. 190 lbs, 6'1". I am a good athlete and I am confident on my bike and getting better. I have been riding for 2 yrs and can stick with the pack. Will the 450f be too much on the trail considering I do a lot of waiting & slowing for my wife and neighbors kid. (BUT you know I will love the 450F on the track!!) OR Do I get another 250f which is sure to have power gains over my current 250F. I will suit me better on the single track trails that I ride on. (BUT you know I will be wishing I had the 450f on the track) Which is the lesser of two evils? HELP!!!!
