Ask a rapper! :thumbup:
As far as I now, you probably wont find any FZ6/R6 rims in chrome. Stock style rims anyway. You would have to take your existing rims to a chromer and have them chromed.
I know of at least one member here who stripped off the paint and took them down to just polished aluminum (chrome looking), but he says it'a a lobour of love as you have to keep polishing them to keep the high shine (about an hour each rim I think).
I would try to search out a local chromer and talk to them about what it would take to chrome your stock rims....or else buy a 2nd set of stock rims (maybe a used set for cheap) and chrome that set.
