I came from a r1200rt to the GTL. I'm 5 ft 10.
It is heavier but feels lighter once riding. The biggest difference for me is that I am sitting "in" the bike rather than "on" the bike. This results in a more in control feeling of the bike for me.
It is more maneuverable at low speed but I'm always aware of how easy to would be to drop it if not careful.
Both feet now are flat on ground rather than being tippy toes. It gets to ball of the feet when on the 2up rider setting.
It comes with either the low or high seat. I got the low. I've since learnt that the high seat is actually a comfort seat. Same seat just more filling and hence more comfortable. I may have chosen that if I knew that before. May change anyway to a RDL. Had a Corbin on the rt...was ok but service and quality were crap.
Most riding is one up and a heap of fun
, but my partner is now excited to go for a ride rather than because we "agreed to go" before. Her feedback is it is far more comfortable and easier to handle the curvy stuff. On the highway she could to sleep!
It is a very different bike to the rt. I've had moments of should I have done it.....
...no I haven't. Just kidding. I love it every moment I'm on it. And many others when I'm not.
