I installed the HD long reach highway peg mounts today on my 2017 Tri Glide. I needed the long reach version because I am a shorter guy. These were long enough to put my foot pegs where I needed them. I set them up so I have two useable foot positions. 1st position heal resting on floorboard and top of the foot resting on the highway peg. 2nd position foot up on highway peg off the floorboards. Both of these positions are very comfy for me.
I am very happy with the results. They also tuck up nice when not in use in the down position.
Ride Safe All,
