I believe they have that option because the twist locks have been known to fail on a dual-sport bike that gets use off-road a lot. The jarring eventually loosens them up and you get rattles. In extreme cases they have failed. Keep in mind for street use and occasional off-road they are fine....I been using them for over a year without issue.
