Difference in Coyote XP and widetrack

I am looking at new karts for 206 Junior for my son.
I have looked at all the leading karts. My question is with the Coyote karts what are some of the differences between the XP and the Wide track. Different size tubing/ configuration? Width? Looked at the website and cannot tell.

From what the website says the xp is more for experienced drivers. I have not seen any data that shows the difference between chassis with same driver I could be wrong but if so can someone please post. I would like to know as well. I have a 2010 xp and I’m not an experience driver but I have no complaints
