Larger Dirtbike Needed

At the moment, I have a super small dirt bike that can fit someone half my size. I am trying to raise enough money to get one that I can actually ride and enjoy. I do not have enough money to get a bigger one, and my parents cannot help me with it either. All I want to do is be able to ride a bike without cramping up and have one with enough power to haul me around with my friends and family. Riding is one thing that I really enjoy in life, and with help, I can finally get closer to having my dreams become a reality. I am looking for the best 250cc model that is green-sticker for California. If you are able to help me, thanks a bunch. Words will not be able to say how much I am going appreciate it. Any extra money raised from this will be put towards gear to make sure I stay safe while having fun. I am not expecting for the amount set to be filled but any small amount helps. Please share this link with others. Thanks for your time and help, Jordan.
