I bought a used 2012 RTL this summer with 4,500 miles on it. We really enjoyed it but only rode it about 700 miles. I am considering trading it off for a new 2016. What are the major improvements since 2012? Obviously the larger engine, slower RPMs and better gas mileage. My wife and I ride 2 up and we weigh a total of about 375 pounds. The 2012 doesn't seem to be a real power house with that weight. I bought a cargo trailer but am a little concerned about being under powered. How much more power and improved gas mileage could I expect to see? The dealer was trying to convince me the handling has improved from 2012-2016, but he could be blowing smoke.There is nothing wrong with the 2012, just thinking it might be time to upgrade. What are your thoughts? Thanks in advance.
