Updates to show reinforced swingarm, side struts, and rear fairing mounting stalks.  The added reinforcements to the swingarm are  made from sections of the 1" x 2" tubing.  The stiffeners at the front have to clear the links and the pivot (rocker arm?).  The side struts are added to ensure the subframe is strong enough to resist the spring forces and support the rear fairing.  There are two "horns" sticking out the side which will support the rear fairing mounts.

I guess it's just one at a time!

Here you can see the stalks at the side of the new struts that will support the rear fairing.    The top view shows the set screw collars which I had to make as they aren't available locally.  They are welded to the swingarm as well as to the stiffeners at the front.  Everything is now tacked in place.  The next step is to strip down the frame, finish the welding, sandblast, and repaint when the weather permits.

Looking great Tom!! You are among several people I know that are adding rear suspension to their Bonneville racers before next year. You have started a trend!
