Any wheel changes? Pics please

Instead of making the rear wheel better looking with stickers and hubcaps, have many people changed their wheels?

I saw a few of them Some people use the 650 or 400 cc wheels I've read there is a mod to do on the wheel to fit the rear.
They do change as well there mudguard for the one of the 400 cc model.
