I was going to order those way back when, but saw this review on them which changed my mind:

Not for the F6B

These are advertised to fit the F6B. They may work great for standard Goldwings, but NOT the F6B. They raise the passenger grip handle rails (that extend over the rear deck) by nearly one inch (1"). The rails should be flush with the rear deck. The passenger back rest can't be used because of that, and the rails and trunk don't look good.
