thought the reinforced frame was in the back only and on 2012 and newer? at least thats what i can remember from all the debates a decade ago
It's a dual frame but in some areas, the frame is double walled and gusseted throughout the frame as well.
The little gussets you're mentioning were added later on and is only at rear where the frame bends over the front of the rear tire.
You can buy them and have them welded in or do it yourself.
They did this because back in 2011 someone ran a run without pre-running the trails.
I think it was 6 Raptors and 4 of them bent that spot in the same place.
And they all had stock rear springs!!!
