As all the guys said above, this is the right place to be regarding Q/A on R65!! Welcome!!
I started with a regular nylon pair of saddle bags, you can get a bunch at amazon or ebay.
Now, regarding solid racks and hard cases, I went with the Krausers, which you can get at eBay. I personally couldn´t find a pair that had a working lock, but well, that´s no biggie.
What you need to be careful is to find a rack that actually fits the cases you will buy... sometimes they are sold as a whole pack, but most of the time, some people have the cases and some have the racks... Before you purchase, I advise to ask gurus in this forum, to make sure you have everything correct.
Good luck, nice bike!!
