Pit bike and which brands model are specific pitbikes.

Hi all, was looking at Pit bikes and wondering what one is the right one for me. I’m 6’6” and about 270lbs. I was specifically looking at the KLX110L, and was thinking about buying new because there just doesn’t seem to be any on the market on Craigslist or offerup, so yeah. But I want to take all suggestions before I do, so yeah, hit me up! All insight appreciated!
