I've been running it for three years now in my 3 bricks. No problems. With three bikes, fancy oil gets pretty expensive, and this stuff is pretty highly rated for film strength, high temperature operation, and additive package.
Engines sound fine, I don't see any metal in the oil at changes, compression is good, the sprags work, and the cylinder head is spotless under the valve cover. The only thing I have noticed is that oil consumption is about a quart every 2000 miles now. It was about 2500 miles per quart on 15w40. The plugs are maybe a tiny bit darker from the extra oil getting past the rings.
