I would like to know what kind of differences there are between the 2018 Goldwing vs the 2019 or 2020's. I have a dealer in my area that has a good discount on some brand new 2018's. Also what do most riders recommend for add-ons other than stock? I have a 2010 with only 70,000 miles on it and I'm 66 years old so I could probably ride this one until I'm done riding. Plus I'm only 5'7" and 140 lbs so the 90 lbs difference in weight would probably be a big plus. Thanx in advance. Link Leary.
