I am 6'2. purchased a 2015 RT. seat uncomfortable.
does anyone have any experience with a Tallboy seat or comfort seat?
First, welcome to the forum. Next, when it comes to seats a few question need to be asked and answered.
First, are you planning to ride solo? If not most of the "Tallboy" types of seats infringe upon the passenger's space severely.
Second, are you looking for leg space or handlebar reach?
Third, are you planning long trips or short,(less than 200 miles)? The reason for this question, long trips you will need/want a back rest, unless you are planning to pack the area behind you with something.
Of course, Corbin comes to mind, but look into Seat Concepts and Russel Day Long, I am sure their are many others but I have had experience with the ones listed.
