I don't see the big draw in being sponsored by most teams that will offer it to you unless you're a top rider, I spend tops $100 every year-year and a half I ride, and my scooter is solid.
It's threads like this that make me want to kill someone. Finding the easiest company to get sponsored by should not be ur goal. You should want to get good and then see if any companies want to sponsor u. The real practical reason of wanting to be sponsored is so that you can get free parts because you break them.
