I don't see any magazine reviews, but a quick Google search of "shinko 705 review" returns a lot of user reviews from various motorcycle forums.
They are on ddventure type bikes like the KLR650 and DR650, but then that is the market for the tire. I can see why you would use them on an SOHC4 if you live where dirt roads are common, but I suspect most of us ride our bikes on pavement and so wouldn't really consider a dual sport tire when shopping.
