I'm wondering what kind of bike-to-bike communication radios anyone is using and found to be satisfactory and can be connected to the motorcycle 12V. We rigged up CB Radios in the 70's - 80's on road bikes with acceptable results but speed equalled more noise. It was very useful on some long-distance Dual-Purpose bike vacation travels. I've been more of a solo rider but I'm beginning to find other retired riders of like interest in finding something lighter, smaller, remote push-to-talk button, etc.
I was looking into this recently and it appears that Autocom is decisively superior to anything else out there. It's also more expensive than everything else I found... They have a few different models in escalating feature set. Their comparison matrix is pretty good. Check out some of their demo videos, their noise-cancellation seems to work extremely well. http://autocom.co.uk/wired-motorcycle-communication-systems.html
