even though my 1981 suzuki gs 450t wasn't on the fitment list, it did in fact mount up quite nicely. after a couple tries, i had it adjusted to my great satisfaction. i can ride to speeds over 85 mph with no wind buffeting whatsoever. this is with a fairly upright sitting position. super great in the colder temperatures. i got quite a few compliments and "wish i had one(s)" when the fall came. as i said, it mounted up easily and was easy to readjust to my preference.
