howdy, im new here & i currently have a yz250 2 stroke which i am trying to sell. the next bike i want will either be a yz400f or yz426f, 99,00 or a 01 model. just wondering what the differences are between the 400 and the 426 and do u think i could handle it coming from my 250 ?. i can handle my 250 fine and throw it around easily. im about 6.2" and probably weight about 90kg. also could u post some pics of your 400/426's in here.
