Help ripping mario kart wii bikes

[Waxylotl]

Hey so this is my second time attempting to rip something, i've found it pretty easy to rip from mario sunshine, but, using the same switch toolbox tool, I am perplexed why I can't look at models from mario kart wii, I import .szs into the editor any file labeled bike, but all there is is one .ikp and a bunch of .brres hexadecimal files. I can't find the models to save me!
