I run the BRP
rubber mounted clamps with Pro Tapers. I am a high mileage rider and stock vibration is not acceptable for long rides. I got the BRP clamps from Scotts
with my steering damper package. I am very happy. They offer 3 different rubber compounds, soft med. hard. I have the medium and it dulls the vibration to low frequency range. Make sure you dont overtighten them. Your bar ends should be able to move forward and back 1" at the tips when you sit on the bike and load up the bars. These mounts significantly reduce shoulder and arm fatigue. I am surprised more off road riders dont use them.
