After installing a fender eliminator system on your new R1, you will be left with a hole under your tail where debris and water can enter your trunk if not sealed off properly. We designed one of our popular undertail closeouts for that void so you can finish off the clean look of your bike without breaking the bank. It is CNC machined alloy aluminum with a durable anodized finish, and the shape of the closeout is sculpt machined to match the exotic lines of the R1. Be sure to check out our Elite-1 Fender Eliminator for this bike for a truly unique elegant way to clean up your tail!
