I've read that the pillion off of a C90 was mounted on a C50, but there was no mention about being a direct bolt on or weather modifications were required. Has anybody done that mod? All that was said is that the C90 pillion is wider than the C50 pillion. Does any of the members who have replaced the original with an aftermarket have a C90 pillion that they're willing to part with? Any info that you can share would be appreciated.
