I am almost 15, about 5 foot 7 with a 33 inch inseam, im currently on a cheap atomik fuse 140 that i got to learn on, i am looking at a wr250f but im worried the seat will be too high, i ride my grandpas kawasaki 250 and its a perfect size but i want my own bike. would it be worth possibly lowering the bike as id really like to get a cheapish bike in the 230-250cc range.
