I suppose it depends what you want from your bike, I have a 79 and my brother had a 82 I rode my brothers bike a few times and as I do not generally try to blast every where it made little difference to me. I have regularly ridden with friends who have modern bikes and kept up as long as they ride sensibly and don't get drawn into testosterone FTL fuelled stupidity, the handling on bends is as good as anything on the R65 (maybe due to the weight ? and low centre of gravity) but if I were to get a younger model I would have to fit Clamshells as I think the plastic air filter is butt ugly......................
