The Acerbis X-Grip frame guard serves a dual purpose. First, it allows the rider to protect the frame of the motorcycle from wear. As a frame protector, it keeps the bike in better condition over time. But the genius of the Acerbis X-Grip frame guard comes in adding a second purpose: grip. That's right, not only does the X-Grip serve as an excellent frame protector, it also makes it easier for a rider to hang on to the bike. As the name implies, it's a frame guard that adds more grip for the rider.
