Thank you all for replying and for the kind offer Cliffbase. I have custom made earplugs from ultimate ear and have tried various helmets from shoei, arai and shuberth. I've spent a fortune on screens and the extenders. I ended up cutting the screen on my XR right down so that it was almost a naked bike and tried an MRA but never really found the right solution. I'm quite small at 5ft 8 so just wondering whether being more enclosed in a big old GSA with a massive screen and bodywork, winglets etc might be the answer. I will of course test ride it's just that sometimes on your test ride day you get calm weather and all seems good and then the real world hits while you live with the bike for years so I was interested in people's thoughts on the comparison.
PS I just can't do an RT. It's nothing personal I could just never bond with an RT. I would be full of self loathing. Every ride.
