the raptor 250 is a great choice, umm but what age are you??? if you think your not gonna grow fast and put on some pounds get it, im 5'6'' and 125 pounds and i ride the sh*t of mine and it still in one piece and not 1 problem at all, just gotta take good care of it
 
my advice, rappy 2fiddy all teh way, i had a blaster that was done to the tits but the 250 is alot smoother and easier to ride, which makes it easier to go fast, and much roomier
