Not sure if there is a thread on this already but I recently watched a video on why not to run frame sliders because they can actually tweak your frame, if you low slide at a high speed. The video stated that engine cover/clutch cover sliders are the way to go. I had a stunt cage(came with it when I bought the bike) on my bike but I find that too bulky for daily use. Race rails seems to sit a little more flush and I like the look. What is everyone running on their Zx6r?
