I would agree the 2014 and later 1600's seem to be bullet proof. I was looking at these bikes for a short while and did a lot of research. 2014 seems to be the golden year. For some reason I do not remember a lot about the 2013 model, all my research seemed to point to 2014. Check out the 1600 user forum that is where I did a lot of my research.
