I bought an 1150rt with a Rich's custom seat and thought how cool is that until I went more than 200 miles and it was just killing me. Living in Seattle I called him to see if he could modify it, Well no way that was going to happen. I went in and he totally rebuilt it from the ground up and made so many changes to make it fit ME that there was no way he could have just made minor adjustments. Sat in his shop all day watching it go through all the steps. There was a lot to it. I then went on a 3000 mile ride and found that the seat was still not right and call Rich up and made and appointment and at no charge he made all the required modification like he should and said if it is still not right to just let him know and he will do what ever is required to make it right. Bottom line it fits me and only me now and it took a lot of work to get it right for me. So without you and your measurements it would never be right and that is what you get when you buy a custom seat.
