I own a RT. For the most part I love the bike. The only complaints I have are: What I would call a lot of driveline lash, a lot of throttle lash and I hate the mirrors, but that is easy to fix(seat too). I tried adjusting the throttle cables at the grip, but it didn't help much and it could use a quick turn throttle, if you know what I mean. I've heard the throttle by wire on the GS is a lot better. That said, the ergos on the new RT look more sporty and less adjustable, meaning look at the handlebars. If I ever get another BMW, it'll be a GSA. It fits me a lot better.
GSA's are great bikes. I tend to favor bikes that have a touring look. You can't beat the seat to footpeg relationship on a GSA. Lot's of room.
The only fly by wire I have experience with is the 6-cylinder. I really have no opinion on it as it felt a bit strange to me but again I have always been used to a throttle cable. I don't like the 6 as it is too low to the ground and it does have substantial drive line lash. We had a few customers complain about it so I contacted BMW to discuss. Their answer was the driveshaft is working as designed. I then asked why they designed lash into the system and what were the benefits in order to explain them to the customer. Of course, they had no answer and that ended the phone call. I am sad to say you cannot rely on NA's answers. They must all attend the same class because no matter who you talk to the denial is always the same.
