Hey Ed. I am brand new to this forum and eager to learn a bit more about my new/used ST4. The previous owner of my new/ used ST4 and another motorcycle know-it-all said that the noisy clutch is nothing to worry about. It sure quiets down when you clutch it in neutral. He said you just don´t notice it when you are ripping down the road and I had to agree. I had another guy say he actually liked it a lot. I got that same feeling with mine. Brushpuppy
