I'm curious about the wobbles, or rapid weave since I viewed a British chap in the Seventies at a track showing all bikes ridden in the film go into wobbles, and then how to stop them, on YouTube. Including an R90s in what appeared to be standard trim.
Have owned a few bikes, one of the things always done at some point was to hold'em WFO to see if they'll pull high RPM in high gear, just for fun and to see how fast they go.
Maybe I was lucky, but at any speed never a one started wobbling. Not at 30, 45, 65 and on up. Even wiggled the bars to see what would happen. Always snapped back to straight. So when I saw the BMW S type wobbling down the track my eyeballs fell out. Never saw that before. Very strange and likely to scare bejeebers out of non motorcyclists. It was the wobble-ee-est film I've ever seen. Don't remember the tag, but fun in the dead of winter.
Sorry if this was on a thread here, but it's still in the curiosity bank.
