I currently ride a 2005 YZ 250T but am thinking about switching to a new YZ-F 250 or 450, I keep waffling. I had a 98 YZ400f back in the day, wasn't crazy about it in the woods. Ridden a 250f ,alot of fun but in certain situations I need more power(BTW I am 210lbs). I do all kinds of riding but the stuff closest to home,where I ride the most, can be pretty tight. Does anyone out there race a 450 in the woods, can you give me pointers and opinions on choice of displacement(250f ?) or bike set up on a 450 for the woods i.e. flywheel weights,rekluse,suspension etc. ? Thanks in advance.
