I have what looks to be a RDL or Meyer seat on my 03 13A. It came with the bike, and after a month or so of adjusting and riding, I can definitively say I don't care for it. Both the front and rear are done, along with a backrest.
RDLs are "Built" for the person ordering it. So, if they are larger or smaller than you, there's a good chance that that saddle won't work for you.
