I've been looking for a dirt bike but I don't know what size bike I should get. Im like around 180 and 5 foot 5 or 5 foot 6. I plan on dropping like 40 pounds just to be faster on any bike I get. I want to race ama. Oh and I used to race ama when I was like 6 and haven't raced bikes since. So I mean Im stuck. I've been looking at 250 4 strokes. Im barely touching in regular shoes. So could some help me out and direct me to a brand and size bike I should get. My experience level riding dirt bikes isnt that good. I do ride fourwheelers occasionally and I've hit 60 and faster. Ive called dirt bike shops and everyone says that because of how big I am I should get a 450 4 stroke. I just want a last word before I waist a couple grand on something that won't fit.
