Should I get 2 stroke or 4 stroke?

Okay so hello I'm 14 years old, 175-180 ish pounds where I live is mostly in town and there aren't a lot of tracks near me that I know about and I'm I want to get into dirt biking but with everyone's opinions that I see I'm finding hard on which bike is best for me and I guess I just need help on finding out what I should go with as I will most likely be riding trails and streets .
Best to start on a small displacement 4 stroke (300 cc or less) and fuel injected. There are several street legal options (dual sport) that are plenty trail capable and low maintenance. Another factor is your height. If you’re shorter in stature, there are lowering kits available for most models.
