+2 for Highway Dirt Bikes Ultimate handguards, for several reasons other than just the RAM mount capability:
1) The aluminum guards themselves are bomber tough and don't bend easily like the cheaper Acerbis Rally Pro and similar guards.
2) HDB guards securely bolt into tapped and threaded bar ends, unlike the rubber-covered expander bolts on most cheaper guards.
3) HDB guards securely bolt to a HDB top clamp on the inboard side, unlike the cheap crappy clamp that go around the bars on the cheaper guards.
4) HDB offers option for integrated folding mirrors, unlike anything else on the market.
I originally had Acerbis Rally Pro guards and hated them because they would always spin when I really needed them to protect the controls. Eventually the inserts broke inside the bar ends. I have HDB Ultimate guards now and love them.
Here are a couple of photos I found on the web that show options for installing RAM mounts in the HDB top clamp. There are various top clamp configurations available. You can see more info on the HDB website. HDB guards require aluminum fat bars to accommodate the tapped bar ends. The stock 7/8' steel bars aren't thick enough for tapping. HDB sends a tap with the guard kit, or they'll tap them for free if you order new bars from them along with the guards.
