I like the looks of my
9" wide rear fender so I removed the gaudy looking stock pillion seat.
(I plugged the three screw holes with plastic buttons which I painted to
match the
fender so it could restored to stock in the future).
But there are times when
someone wants to ride so I needed a quick remove/install passenger seat.
I used a piece of ½"
thick high density foam rubber, the interlocking flooring that's used
for childrens play areas. I cut it 6" wide X 10" long and radiused the
corners. I used six 2½" diameter suctions cups from Michael's Craft
store, the ones that are 2 for $1.79 with the metal hooks on them. They
will be glued to the smooth side of the foam. Lay out the suction cups
to leave ¼" from all the edges. Mark the center locations on the foam
and push through an awl to allow expansion of the Gorilla Glue. I used a
½" masonry bit to drill the holes almost through the ½" foam. Wet
the holes with water on a finger and apply Gorilla Glue to the suction
cups tips and grooves. Insert with the cups tabs pointing outwards
toward the edges. Weight it all down until the glue dries.
You will be gluing the
textured sides to each other. When the glue dried I mounted the assembly
to the fender and pressed all six suction cups down. I cut a second
piece of foam larger than the first for the second layer and used
contact cement to adhere them together. Let this dry overnight installed
on the fender as this will make and retain the final custom contour of
your seat.
This is the "formed" and
dried assembly prior to sanding the edges and corners smooth and
finished. The custom contour for your fender won't change now.

pad on the fender.
Lifting the little tabs on the suction cups in sequence will release the
seat pad from the fender.
This is what the sanded
pad should look like, wiped down with a damp rag and allowed to air dry.
Keep it nice and clean for covering.
I used a fuzzy backed
vinyl from Joann's Fabrics for the cover. The contact cement will cause
it to wrinkle badly but don't let that scare you. When you're ready to
press fit the cover on after the contact cement dries (about 15 minutes)
it can be stretched to fit and the wrinkles pressed out. I first glued
the vinyl to the top of the pad, then the edges and then the under edge.
Using a hair drier to soften the vinyl as you're putting it on the foam
helps keep the wrinkles in the corners to a minimum.
