Remember---get all dolled up in Electric lines, gloves, etc and if you are serious riding, you can darn near freeze to death when the electric stuff doesn't work for whatever reason.
I almost frooze near Monterey Mexico when my electric vest quit. AND and I had no feather jacket along to wear under riding suit.
Also, hooking yourself up to wire, etc, pain in butt to me. Having ridden for 55 winters and several mid winter coast to coast, both solo and sidecar---feathers work best for me and professional quality riding suit----think next bike should have grip heat.
Why ask electric system to do something it wasn't designed to?
Actually riding in the cold can be fun----sidecar in snow real blast. Just need the right equipment to keep warm.
