this is how the sales system works, they want you to try other models knowing it will be different and there fore " nice" . I bet when you take it back they casually ask how it went on the RT, " oh it was great thanks " " come and sit down have a free BMW coffee and we can talk some figures"
You will buy it and when you do ask for the £450 service fee you just paid on the GS to be deducted.
The RT is a superb mile muncher , the bars can be sorter with risers that move them up and also back for more comfort
