I bought this recently as a "2014 Infiniti Vortex", but while doing some research for set-up for asphalt I have come to question that ID. It looks like all of Mike's newer chassis had a rounded front hoop & one continuous curve on the right side inner rail. This chassis has neither.
The two photos are the only ones I have available to post because the kart is an hour away right now. Can someone ID this chassis?
