I think think it's loud enough to get stopped or maybe not. I feel I might need ear plugs but can't wear them. It'll certainly get me noticed etc but hopefully not from plod.
I'm looking for other ones even standard. The only other bit I'll change is the bars as someone before me as put them under the yoke and when you're full lock you're touching the fairing.
Apart from that it seems fine, I had one years ago but standard and wanted it noisier. Now I've got another and it's too bloody noisy
