Never had a proper tank slapper on a motorcycle, plenty of weaves that stopped with either more or less speed. However I had a bicycle that I had three tank slappers on , all at 40 plus mph, all downhill. I managed to rescue the first two, the third got me though. And even as it was bucking like a horse I was thinking relax your grip dont touch the brakes, but it royally spat me off!
My friend was close behind and he said “ I thought you were going to save it as you used both sides of the road”, so did I.
As others have said , good to see you are posting and that it doesnt put you off riding at all.
