Yeah, easiest by far, as pillion seats can be had for $50 if scruffy, and you will remove and ditch the pad anyway. They are designed to hold a lot of weight obviously and can be easily fitted or removed with just 3 Allen head bolts when travelling or not. They are predrilled with wide spacing bracket tabs for fitting any sort of rack or size you like.


Or, get one of
@Mittzy racks or mount the std rack with Mittzy's Quick Release sissy bar mounts which can be adjusted to fit those cheap painted Easy Brackets too.

Otherwise a RIVCO rack which are rare, or a Corbin seat and US made aftermarket rack
* that fits the riders backrest post.
* @WyldCFH bought one and I got his from the Classifieds when he sold his R3R
