This is my current set up with my second GoPro Session camera to my 2014 Triumph Thunderbird LT. I added the second camera arm 2 weeks ago to the RAM mount arms and balls. The PVC pipe is DYI and attaches to a ball-mount on the aux light bar. The top is adhered to the screen and the RAM has the ability to add rubber-ball mounts easily. With this, i can shoot forward and back at the same time and it makes the roads/ride much more interesting on editing (IMO). Plus, i don't miss anything i didn't see while riding.
This is a 5 year accumulation of efforts to get the video i want to get while i'm riding. I went through numourous set-ups to get here and i'm satisfied with the results. Now, trying to find an interesting narrative to share so the video has a point other than riding here to there.
*I love the waterproof session feature.
