125 vs 250

debating between a 125 2-stroke and 250 four-stroke

if i get two stroke I am deciding between suzuki-yamaha-kawasaki

if i get four stroke, i want honda

I have a kx100 right now, but at 5'10 and 135 lb, its starting to feel too small...i love the bike and everything just needing a bigger one

any suggestions??

thanks
