The Cali III and Cali 1100 seats were the same. On my last Cali III I fitted a Cali Vintage seat. I like the one piece better and it doesn't dig into your butt the way the two piece seat did. Seat latch won't mete, of course, but I compromised by putting industrial Velcro on the seat pan and the top of the rear fender to hold it on lightly. Much more comfortable than the oem seat and the skunk pattern looked great on it.
