This bar ends have the S3 patented fixation system that allows the throttle side bar end to rotate with the grip and works as a bearing for the throttle. This keeps mud, dirt, rocks and water out of your throttle to provide consistent and smooth operation. Take a look at the video below to learn how to install these. They feature an anodized end cap and S3 laser logo.
