Re: 1978 R80–7 cruising speed
I had a 75/7 and three 80RTs for work in the UK. In those days I could cruise at 80mph = c5000 rpm, no faster as I didn't want to draw attention to myself. All did 250,000+, with a ring change about 150,000.
I ride a 50/2 these days, partly because it's lower, lighter, simpler and partly to reduce the temptation, so many cameras etc nowadays but in France it's even worse. Just like with my Dad, the best times were always when we were young.

Re: 1978 R80–7 cruising speed
My R80RT went 125 K miles before the pistons started slapping the inside of the bore. I am now at 220K miles and things are still good since that rebuild.
My R0RT seems happiest at 70Mph, but, I am usually only doing 60 due to speed limits here. It is also happy to 75 or 80 all day long when I get the chance. No oil consumption and smooth.
I would expect my major engine wear is due more to the amount of start and stop, up and down shifting and such which I AM aggressive with rather than straight cruising. If I were a bit gentler on the bikes, they might last longer between engine rebuilds, LOL. St.

So strangely, despite the heavy mileage, the bikes probably wore out less quickly than bikes with lower mileage but ridden harder or with lots of short runs.

Re: 1978 R80–7 cruising speed
While I have a lot of miles on my R80RT, I have a friend with similar milage on his bike and he has far less trouble and repairs due to the riding conditions he has versus mine. He is in open country with lots of long stretches little up and down shifting and braking.
I have seen a few posts where fellows write in and pooh poo downshifting as an evil. I personally have never bought into that and since I haven't, I take them at their word but, am not interested in changing my ways. St.
