Keith, I have one on my YZF420, and I like it a lot. I had an older Emig clamp on before the RG3. RG3's is very solid feeling with a huge decrease in vibration. They are high quality and look trick on the bike :) .
I tried the RG3 clamp as well. Over all good clamp although it did not move my bars far enough forward or tall enough for me... I run solid mount Emig's and love them. Vibration does not bother me, to be honest I can't feel vibration in my hands with the solids mounts or any lack there of with rubber mounts. But I am a slow guy. The RG3's do look SUPER trick though. It's all what you prefer.
