Thanks R-Rated!
I'd like to mount on the chinbar, I really only use the modular aspect of the helmet to get in/out, get fuel, for breaks, etc. I never have it up when I'm rolling. So I like the concept of the Chin Mount, and it looks like the model for my helmet does leave the vent open (which is important, that vent makes a big difference!
I just tried that POV on my last ride. Put the Insta360 down near my front tire and then near the rear. The front tire view, IMHO, was pretty neat. I ride a S1000XR, I don't know how much lean angle it takes to get a peg to spark, but I can tell you, 47 degrees won't do it! The bike records lean angle when you ride, I've hit 47 and not scraped, so, whatever it takes to get that peg down, it's a LOT of lean. 47 on the street is, between us, pretty dumb/sketch, I only do it at relatively low speeds in 180 degree turns, but that's a LOT of lean for the street!
I capture the audio on a Tascam that's under the seat. I don't do any talking in my videos, I have a voice for silent film.
I'm trying to build out videos that show the experience of riding on challenging roads and focus on the bike/road more than myself as the rider, I'm just there to keep the thing upright. So I just capture the engine sounds and then sync it up in post (which is a massive PITA because the Insta360 cannot do a gapless recording).
