I had 2 H-2 750s back in the 70s and 80s. I nevrr had one wobble on me. The biggest issue for me is they would lift the front wheel so smoothly you had to really watch how high it was getting.

I had a Z-1 that at times would be evil. Buddy of mine was going to show it who was boss, and it spit him off onto the blacktop.

I just bought my old ZX-14 back. Compared to the old bikes it's a 190 mph Cadillac.
