Performance Machine Vision Series transmission covers give you the power to view what goes on inside the heart of your bike's gearbox. The UV- and abrasion-resistant polycarbonate lens is framed by a 6061-T6 aluminum bezel to add structural integrity, as well as provide an even distribution of clamping force to eliminate cracking. All Vision covers are precision CNC-machined from billet aluminum and come complete with chrome hardware and any required gaskets. These intriguing see-through accessories are a great alternative to the mundane stock parts—and are offered in Chrome, Black Ops, and Contrast Cut finishes.
