Tritons, Prodigies, Legend M5, Riot, and Seay Rivals are all great chassis for MX/two cycle applications. Those have component backing from the companies to have them race ready off the jig which makes life a lot easier and is cheaper than taking a barebones chassis like a titlist/deuce/pursuit/ or any other chassis for that matter and trying to convert them on your own dime and effort being that they are not made to accommodate those items. Most newer base chassis for clone racing don’t leave room for anything bigger than a 3QT tank too, which is quite a headache when you need fuel capacity. That said, if you choose to buy a UAS/Open prepared chassis or buy a standard model and convert it yourself (and do it right) you should have a kart that can generate roll speed and turn if you get the setup right.
