hello all, i'm looking to get a new bike...the yzf 450 or a two stroke. i've always ridden 4strokes, so i'm leaning that way. anyway, got a couple questions about the 450. i ride mostly trails here in FL. terrain has sugar sand, whoops, mud, to hard packed wide trails and tight woods...basically everything. how does the old thumper handle the trails with the 4 speed tranny? not worried about weight cuz current bike is a dr 350!!! would the 5 speed 2stroke be better?? also, what is the approx. mileage on the stock tank?? just in case...i'm 26, 6 ft, 190 lbs. Any info would be appreciated! **if anyone who reads this and rides in FL at ocala and/or croom, let me know what you think of the 450 in these areas...i've never been, but my riding buddies and i are planning a trip when i get my new bike.
