Yup just two sided tape but make sure you are very easy on them. They will break really easily.
Heat them up with a hair dryer or heat gun, but yeah just two sided tap holding them on.
I went with the CF one since they only cost about $30 more than stock ones. But as you can see Sedar had painted some bezels when he did the paint on my bike. I like the layered look, that the CF gives it with the paint under them.
