I read this post with great interest, especially the "push steering" which was a new concept to me, I never heard of it before and when I took riding lessons I was taught to lean into corners.
But a few days ago I collected a very un-Harley vehicle, my mountainbike after a rebuilt and thought I'd try out what I read. And would you know, it also works at mountainbike speeds, which are well below 35 Mph.
Riding along at a reasonable speed, say 15 - 18 Mph when you push the left handlebar away from you, expecting the bike to take right turn, it "falls" to the left.
So riders fearful of trying this move on their Harley, might use a mountain or similar bike like me, it really works.
