Honda should build a 1981 XL500. I had one, 20 years later, and it was the best dual sport I've ever had by far. Way better than the KLR650 and XR650L, and I'm assuming the DR650 as well. Unfortunately the PO had not treated it well, and the engine blew up. And as is typical for Honda, I could not get parts to fix it.
I won't spend more on a bike than I think it's worth, but if it's a good deal, I don't seem to have a problem buying bikes I don't need.
