Hello! Well i need some help on choosing a new bike. So im decidng between a yz250f, and a yz450f, i already ride a ttr125,which im selling, but would i be able to handle the 450. I rode my friends 250 2 stroke, and its jetted, maybe bored, and has a performance pipe and all that good stuff, and its puching about 300cc. I got it to 4th gear no problems with the throttle maxed out. It just felt really snappy. Would i be better on a 250f, or a 450f? Also i ride in woods, jump, and race my friends around my track, and i pretty much do everything. What do you think the best bike for me would be? Also what bike would you get? thanks!
