    the 250ex will not go 50 or for that 55. it goes like 45 and with a pipe and jet kit you will not see a mph increase you will have more power in the gears but probally not alot of gain because of of such a small engine until you port and polish it let the engine burn more and release more. there was a forum a while back that was talking about rev boxs for the 250ex and it got into the 250ex not going to go any faster just more power but depending on how much money you want to spend you will want a bigger quad when you are older and putting money into somthing your probally going to sell later on i would keep it fairly stock and when you get a bigger quad youll be able to get more power out of it with the money you save i know i should of saved my money instead of putting it into my 300 but what ever you do i hope your happy with it

    dude what r u smoking? It goes like 54 and if you add a pipe youll see like 55 tops. But 45 is way too low.
