Ducati now has a cowl for the rear seat on our bikes with the new seat. When I bought my ST4s last year, I asked about the availability of this part, and it wasn't available for the new style seat yet. I just received my new black cowl today, and it looks fantastic! If you like the mono look, it's perfect. The paint matches perfectly, and it definitely looks more sporty. It's easy to install, just clips on the seat edges, and isn't that expensive. I thought it was well worth the investment.
