Buck’s Lowers are a high quality product made in the USA that is designed to eliminate buffeting by preventing the updraft that occurs with the Roadliner/Stratoliner motorcycle at moderate to high speeds. This buffeting can cause helmet shaking which impairs vision for most. This is particularly an issue for operators that wear half helmets. All kits come with 18-8 stainless hardware and instructions. Installation time is about 30 minutes.
