Looks like a modified kart chassis. Looks like an LO or two pushing it along.
Anyone race these?
From the one side wing, I am guessing these are oval exclusively. I’d like to try this,
The caging necessary? I wonder if these are flippier than our sprint karts.
Maybe the caging is so that they can use HANS and a harness.
I don’t know if oval karts are more prone to flipping or not than sprint karts, but I have seen a couple go up and over from cornering force. The weight tends to be down low though.
Not sure the need for a HANS device in a kart. Adding a giant cage just to run a HANS seems like a silly solution to a non-problem.
The first pic might also be a quarter midget/sprint. They have suspension. Hard to tell from the pic.
