Off roading to da max!!!!
Yup, radiator guard/crash bars like thesehttp://www.bs-motoparts.com/KTM/390_Duke/2014/10517/sturzbuegel-3463.htmA radiator guard would be essential also, methinks. Making a basic skid-plate wouldn't bee too difficult since all 4 bottom bolts appear to be in the same plane, probably fab up some 1/2" thick spacers to gain a bit of clearance to the crankcase. The mounting points for the forward upper bolts would be a bit trickier, but still doable. Having the belly-pan as reference will simplify calculating the angle : ) Using some welding rod bent to the same angle as the front portion of the pan would make a good layout gauge for the basic shape and hole locations. Don't get me started LOL.....
