Traded up from our 2013 RT Limited to a new 2019 RT Limited. Getting handlebar shakes and vibrations between 55 and 65 mph. Rides perfect at 75 mph plus. Have taken it into my local dealer and had both front wheels re balanced and drive belt tension adjusted. Much better after the belt adjustment was done, but still have shaking and vibrations between 55 and 65 mph which cause my hands, elbows, shoulders and neck to hurt after riding. Love the new ACE 1330 engine and six speed transmission, but hate the shake and vibration I'm currently putting up with. Dealer is talking about adding a belt tensioner and further rear wheel belt tension adjustments being made. I really like our new spyder, but would really love it rode better. Never had this issue with our 2013 RT Limited. I really believe I have a compounded issue with tires and drive belt. Any suggestions, recommendations are greatly appreciated.
