I've been riding for a while now and i love my Yamaha Banshee and now I want a bike I really want a yz250 not a 125 because I think the 125 is a little too slow I wanna know if I will be able to ride the yz250 and I'm about 5'6" and Weigh 140 and my brother says a 250 is too big for me but I like to ride pretty hard so will the yz250 be a good bike 4 me?
