I use the Insta360 Bullet Time selfie stick kit, combined with the Insta360 Motorcycle Kit and a Sky JFFJ adapter.
Check out my video titled "GoPro Max and Insta 360 Selfie Stick Motorcycle Mount Kit on Harley Street Glide // Setup // Testing" on my channel - it's got affiliate links to the kits I use.
I've been quite happy with it so far, just make sure you have a 2-point mount or keep the leverage down [2ft or less of extension out of the 4ft available]. FWIW, I have a playlist for 360 Camera Tests on my channel of vids I've done, some good, some bad. Lens protectors saved my bacon a couple of times so far.
