Form and Function
It takes grinding, welding and repainting to properly install this seat hinge on your motorcycle. If you don't have the tools and confidence for these steps, please consider another way to install your seat. This hinge works by creating a pivoting point between the nose of your solo seat and the backbone of your frame. The black strap bolts to the underside of the seat; the raw steel bung must be welded to your frame. After light fabrication and repaint work, the two pieces bolt together with the chrome shoulder bolt provided. A light smear of grease on the shoulder bolt and a drop of blue Loc-Tite on its threads keeps everything working tight and tidy for years.
