I was looking at it and wondering why not just back up to the mound of dirt and not even deal with the ramp. In Steve's defense that looks like a small KTM 2T. Very light!!! Looks like a really nice riding area.I was looking at that ramp thinking "not sure I'd walk up that, never mind put a bike on it".
I never questioned its strength only its ability to slide off the tailgate. Also slippery when wet and very heavy.For you city boys, That ramp is native oak cut with an Alaskan sawmill, It would hold my Tenere loading.
This is how I usually load.
