A good amount of people in here are reccomending you to get a 600cc bike, dont do this. I dont give a fuck if youre a goddamned ape man like Brandon or what. Get a Ninja 250R, you will LEARN how to ride on this thing. After you do your Marines stuff u can sell this bike for a decent amount and then move on up to the bigger bike when youre ready and know exactly what to do in any number of situations that can arise while on a bike. The whole goal here is for you to be absolutely comfortable on any machine you hop on to, and to be incontrol of it rather than it being in control of you. Goodluck with your purchase and for beginning your venture into riding.
