When browsing through the official accessories catalog for my Aprilia Tuono V4 Factory 1100, I noticed the carbon front brake air ducts (part number 2S001379). However, considering their high price, I initially decided there were far more important accessories to get first, for example, an SC Project exhaust, a more discreet license plate holder, or better-looking mirrors, so I postponed the purchase. But then, I happened to find the same ducts second-hand, in like-new condition, and decided to buy them earlier than planned. The rest of the accessories are scheduled for purchase and installation during the winter, which you’ll also be able to follow here on the blog.
The first step in installing the ducts was cleaning the brake calipers with brake cleaner. Next, the calipers need to be removed, and the lower screw on the front fender mount undone. The spacers for the brake calipers are taken off and replaced with the carbon ducts, after which all bolts are reinstalled. The caliper bolts should be tightened to 50 Nm (this is not official information, please consult the service manual).
The front brake air ducts improve cooling and help maintain consistent braking performance. They’re a direct product of Aprilia’s MotoGP know-how and racing experience. Made of carbon fiber, they reduce weight while maintaining a high-quality feel. Are they necessary on a motorcycle that’s mostly used on public roads? Probably not, but they do look cool, give the bike a more aggressive appearance, so why not.
