Ok here goes.Ii owned f6b 4 years and loved that bike you all know the ride on that.Then I traded on non tour 19 wing,very nice ride and some softer than the B.Then sold the 19 wing 6 weeks later.Then bought k1600b 3 weeks ago .The ride on this bike in cruise mode is very soft plush..If I had back surgery it would be on short list and would surmise the new tour wing would be good also.Hope that helps
