There are a few options out there for Street Twin bench seats, one of which comes directly from the factory. I thumbed through Triumph’s accessory catalog, so to speak, and found their Brown Ribbed Bench Seat for $375. Aesthetically, the bench seat looks great, adding more retro flair to the already retro Bonnie. The brown ribbed leather with the tone-on-tone embroidered logo adds a nice subtle touch of class. While the flat profile, which replaces the more scooped out contour of the stock seat, looks great, it’s not as comfortable for longer rides. It does, however, solve my issue with legroom, adding 1.3 inches of seat height.
