i got that xposure gyro cover as a freebie. gt bikes had a video out in 1995 called "code 4130" or something like that, directed by eddie roman.
first copy i got had faulty sound, then was replaced by another which also had dodgy sound, so as a small compensation type gesture, the third copy i got enclosed that gyro cover. (but the vid was still faulty
)
khe also did a cover, along with a few others i'm sure, but in 1995/1996, i'm not sure how many people were doing lots of cherry pickers and would have the need for a gyro cover...
