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 donĀ“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
