I haven’t checked these guys in a while but back when I put my cases on my 650 many years ago, the happy trails pannier system was the same for the 1000 and the 650. These guys are out of Idaho and make high-quality no-frills panniers. I’ve been really happy with mine for the money. You might look at them.I own a 2018 1000 and a 2017 650 and looking at side case systems.
I would like to buy 1 rack system and 1 set of side cases ... bolt that rack on the 650 first, take some trips, then later move the rack system to the 1000 and take some trips on that bike.
It is obviously pretty easy to have cases that can go between the bikes, but from some searching around it seems the rack systems are different. Searching and getting a bit confused and thought maybe someone on here has looked into this before?
And yes, I could buy a rack system for the 1000 and buy another for the 650, just trying to be thrifty. (Maybe save $280 or so)
