welcome!! you are exactly my height and weight and i have a 250. its light and you can touch the ground just fine! with extra room to spare. i was told to get something bigger.. but i personally didnt want to take that chance. the 250 is very forgiving if you dont know what your doin. but then again, i learned on my bike, then took the msf course. i also didnt think i would need anything bigger, and still think that.. i dont plan on goin 100+ on any road. but good luck on your decision!
