I carry a Honda CT70 on the front of my pickup. Only 164 pounds, so that isn't much of a problem. Also small enough to not obstruct the headlights too much. I built the rack using two receivers, one on each frame rail. Very solid mount and I also incorporated a front center receiver for hooking trailers to the front. Front receiver always stays on and I add two "buckets" for the Honda tires when I need to carry it.
Have used it for 8 years without a problem. I built it to carry the full weight of my pickup, so I don't think the little Honda could tax it at all.
