I purchased a 2010 tri glide ultra classic in the spring of 2019 , I didn't put to many miles on it but it seemed it was beating the hell out of me and the wife. So I've been looking into upgrading the rear suspension, I see lift kits and 13 and 14 inch shocks, I'm a little overwhelmed, I am 6'1" , 280 lbs, the wife is around 160 lbs, I ride solo about 70 % of the time, kind of leaning towards Legends , any advice would be appreciated.
