Alright, so I've never ridden a dirt bike before and am wanting to learn to ride, mainly because I want to get a Harley and figure it would be best to learn on a dirt bike first. So, my main question is what bike should I be looking to get to learn on. I'm a big guy (350lbs) but short (5'6") and am not looking to spend a lot of money. I'm totally ok with getting an older bike as I don't plan on using it for much more than learning to ride before getting something else. Any thoughts?
