Help is here. More comfort, less vibration, no more "pain in the ass"- passengers this is your solution. The medium fabric Pro Pad helps eliminate the pain. Measuring 14" wide and 10" long this pad is designed to fit most cruiser style passenger seats (Fatboy, Heritage Softail, Sportster, Road King, Dyna's, VTX, Valkyrie, Vulcan, V-Star, Roadstar, etc); it also fits the Rider seat on a few of the smaller bikes (Buell S1, Suzuki Savage). In many cases the sides of the pad will overlap the edges slightly, increasing the width of the seat, which increases passenger comfort. Installation is easy with our two-part system: (1) a sewn-in elastic strap towards the front of the pad that can be flossed between a two-part seat like those found on Fatboys, (2) a strapping system at the rear sides of the pad with detachable clips, adjustable elastic straps and coated metal hooks. These hooks can then be attached to the bottom edge of the seat, to each other underneath the seat, to a rail or the hooks can be removed and the elastic can be looped around a bar. Durable, quilted nylon fabric can be scotch-guarded to repel water if needed. Pro Pad medical-grade polymer is in every top pad, giving you that great ride.
