No one's mentioned the Moto Guzzi Norge (link)
About 560 pounds, so 100 less than the FJR. And it's Italian, so it will be right at home with the Ducati.
Before I bought the N1K, I looked really hard at leftover & used models of the later gen Norge (1200 GT w/the 8v engine.) Reviews were polite but generally fantastic and it appeared to fit all my wants/needs. I thought it could possibly be the great, lighter weight alternative to the FJR.
However... the selling prices were outrageous at the time, even used. Local dealerships were also not negotiating, and the dealer network is/was/remains few & far between. Next point: to be polite, the overall quality on certain areas almost looked homemade or garage built. The dash, for example, was possibly the sloppiest piece of work I've ever seen cobbled together.
Still, the Norge had a certain flair, was pretty to eye, highly practical. If I could've found one at a reasonable price, I would've given it greater consideration.
RE: Chains- modern chains ain't like chains of yore. I cleaned/lubed my N1K's chain infrequently and rarely if ever adjusted it. My only complaint about chains was the mess they made on the rear wheel post-lubrication. Outside of that, never a concern.
