This is kind of a survey. I am used to riding a zx14 with zero back support so when I ride the Goldwing, it is like a easy chair. Purchased in August , so only long ride so far was about 300 miles one day and 350 miles back the next. No issues at all with my rear end or back. Just wondering how much more comfort can I get out a back rest and which brands are good and which are not. Any help as always is appreciated. My ride was down to Poop's pub in Savanna Illinois. Will ride there again this summer. WHAT A BAR WOW.
