Not accents, bag racks. Several are no longer made (Honda made the nicest ones)(and I think Cobras and Big Bike Parts racks are also no longer made for Valk) Pinwall Cycle or Evil Bay may have used. Some not made for Valk
might work, but iffy proposition and may require shimming to match the bag curve. Holes need waterproofed.
MCEs are still made, thinner stock and not my favorites. part no #472-13

Custom World International out of Quebec makes some nice (but expensive) stuff, but french website is hard to figure out.
