I have Hikari LEDs in my 765's headlights (even though I have a 675, I updated the headlights and flyscreen.) They're great.
Something I only recently learned after installed LED headlights for years, is that the H4-ring that's so hard to clamp inside headlights with LED's and their cooling fans, that thing actually comes off. Just rotates and unscrews in a half-turn. Install the ring with the retaining clip, and then insert the LED bulb itself and turn it - instant install. No fuss with that damn retaining clip.
