I wonder if "survival" of bike and rider is as true today, what with the
much more massive bikes and faster speeds and plastic parts...
I don't know, My GS is a 1000cc bike, but I managed to break my tibia riding my 250cc dirtbike 3 yrs ago down in Baja with much more protective gear including wearing trials boots. Hurts about the same if you ask me.
When I got into motorcycles, the popular Japanese and Brit bikes were
mostly 125-250 to maybe 500 cc's, and pretty lightly built. With some of
today's bikes, you'd need a crane to get them upright if they tipped
over. I don't remember what the top speed of my Honda was back then,
probably because I never hit it. I know the speed limit back in the day
on the Kansas Turnpike was 80 mph, but I never did more than 60 or so.
