Description

Ditching the stock fender on the Aprilia RS 660 or Tuono 660 is a pretty easy way to improve the looks, but the one drawback is being left with a pretty large gap on the undertail panel. We set out to fix that. Our exclusive Undertail Closeout design converges all of the panel's design elements into an easy-to-install CNC-machined aluminum component that features a durable black anodized finish. This high-quality kit mounts to your Aprilia's undertail to provide a clean, finished, and race bike inspired look that not only looks amazing, but also prevents dirt and debris from entering the undertay. The integrated wire route hole provides easy access for a license plate light or rain light. Get the style you want on the street and the functionality you need on the track with our TST Industries Undertail Closeout.
