I have an 1980 xs1100 special,and the seat pan is plastic and brittle . I have two other seat but they do not match the plastic one . Has anyone ran across one of these before . It is stamped Yamaha xs1100 SE .

Hi ccjj7,
All XS years had metal seat pans. I wonder if you hav an aftermarket seat? Search posts by Crazy Steve as he did a great job of identifying all the seat pans. There is limited interchange between some years. Do you have one that fits your bike ? as that is all that matters

You have an aftermarket seat, as Phil suggested.
