The difference in power, ( i went from a 1980's z50r mini to a Honda '96 CR250r) it might take some getting used to. I'm 15, and stand at 6 foot 1, weigh about 190, and the power difference for me was like .. O,o .. Holy! It probably wont be as extreme a transition for you as it was for me, since what you bought is a 4stroke enduro, and me a 2stroke MX. But you'll probably end up stalling alot for the first few days like me (better to stall than to flip that kinda bike in my opinion). I wish i bought a 4storke instead.. street legal n stuff.. but , take your time learning on it :D
