Keep in mind that frame sliders are different than what you want to think of as fairing sliders. As a matter of fact there is no such thing really as fairing sliders. Fairing sliders would just be frame sliders that have the possibility of protecting your fairings. The main object of the frame slider is to protect your frame and there’s much debate on how well they do that. When it comes to crashes, you can’t really control what kind of crash you’ll be in that will result in a best case lowside scenario. The best case scenario being that you lowside, the bike slides, and the sliders result in no or very minimal cosmetic damage (like clear coat scuffage). Worst case scenario being you ruin your frame from the frame slider bending with force in the frame. And if the slider catches on something, it can flip your bike into a tumble (more damage) or bend into the plastic and gashing it open (useless protection). That being said, I still use them, but I don’t expect much with the plastics being saved.
And yes, for the CBR (as with certain ducati, suzuki, kawasaki, etc.. models), there’s 2 kind of frame sliders – no cut and through body. No cuts rest on the inside of the fairing. Through body requires cutting the plastic allowing the puck to be outside the body.
