the blaster is a little bit small for a person over 5'10. It is a great bike though and when you pipe them they become quick little bikes. I beat warriors all the time with my blaster. The 300ex is a good bike too but it is a little bit under powered.

 

just to let you know, pound for pound the blaster is a lil bit quicker than the 300ex and definately quicker than the 250ex. soooo, your next step up is a warrior and a 400ex. and warriors really aint that much quicker, if any (given right conditions) than a blaster. but it's bigger

 

i think you will fit i am 6'1 and i fit jt fine

 

you arent to big nig nor him
