Honda Big Red three-wheeler hardtail with "suspension" forks consisting of bronze-bushed lowers riding on chromed steel downtubes... NO LUBRICATION. Yup- dry. Think of how many oscillations a fork goes through, then think of designing DRY fork sliders. The obvious outcome: prematurely worn out AND eventually seized. Sheesh, I knew better than to do something like that when I was 8 years old.
