Except for the '81, the LS was the only version to have dual front disk brakes, so that would add some weight.
Aha! That answers a question that I've had for a long time: Why was my dual-disk '81 relatively unusual for a twin-shock R65? I was aware that a twin-disk conversion kit had been available, so I assumed that mine had been converted at some point.
Thanks to all, and an apology. I've been distracted for a year or two, and I haven't been monitoring the forum regularly, much less riding. (My bike spending the winter in the shop for some repairs and improvements has something to do with it.) I have some catching up to do, both in reading a lot of material here and totally relearning my skills, which weren't all that skillful even before my long break from riding. I feel so rusty that I'm tempted to take the MSF Basic Rider Course again. I'll try to keep track, even if I don't contribute that often.
Prosit!
