It's been a few YEARS since I posted on ADVrider. Too busy with a fixer-upper house and all the other things to do here in the mountains of Northern New Mexico!
Those crash bars do look just like mine but I'm not sure of the brand either. They were on my bike when I bought it back in '99 or so. I once had a reader on the Elefant e-mail list
identify them, but now I've forgotten what they are.
The luggage rack in the photo you posted is different than mine. I got what may be one of the last GIVI racks made for the Elefant to be found anywhere. These others could be Happy Trails.... or... ?
Good luck with your search! The Elefant is still one of my favorite bikes ever! And I've had mine over a dozen years!
