F6Pilot: Mine looks exactly the same, and just on the brake side. I figure that comes with an aftermarket seat.

To all: As far as the rails fitting. Though they were a real pita to install (the seat is too wide on these latest seats). This morning I removed them and it is 90% better. I can easily push them back into place. So something has given over time. Yeah!

Now to work on making the side covers removable ....
