So I got my youngest 8 turning 9 a 2015 RZR 170 …. Over all love it… Nice enough power for him even with my wife with him (she is only 5′ and 100 #’s)…. After a few times out it is clear that it needs several upgrades to be able to ride on even easy trails… Biggest issue is ground clearance…. Only way to not get stuck was to ride the high side of all turns and ruts… My wife can get thru most but way to hard to drive for the little one….he took my older sons ace for a bit with no problem…. So where do I go from here?

1) dump $1-2k into the 170 so can get thru trails but will not be able to take on any difficult trails?
2) trade on RZR 570?
3) trade on RZR 900 trail?
4) trade on Artic Cat Wild Cat Trail…. About same price as 570?

Looking for some help and thoughts… Been going around in circles trying to debate best move…
