I've owned a lot of different motorcycles over the years and here's what I've found to be universally true. Most (not all, but most) OEM motorcycle seats come up short in the comfort department for most people. I ran across something recently that stated that the "model" for a motorcycle seat that the Japanese manufacturers use is a rider that is 5'8" tall and weighs 135 pounds. May be fine over there, but that is not the typical American motorcycle rider. I have found that the basic problem with OEM seats is that they're all shaped the wrong way. The 900 Vulcan seat is a good example. The slope of the rear portion of the rider's seat has the wrong slope to it, and it forces the rider's butt forward, shoving the more delicate front areas into the rear of the tank, while at the same time putting a lot of excess forward and downward weight on the butt bones. (aka, ischial protruberances) Doesn't take long to get very uncomfortable.
Merely installing "better" foam or gel doesn't really solve the problem. That is where the better aftermarket seat manufacturers come in. Russell is a good example, as they fashion the seat to YOUR shape, and so it fits YOU, not a generic one-size-fits-most seat. Mustang is an example of a one-size-fits-most seat that actually works for a lot of people. YMMV, however. And it doesn't help that OEM seats have foam that feels good when you first sit down on the seat, but very quickly, due to being too soft, usually, your weight causes you to slowly sink down, the foam compresses and becomes hard, and you start experiencing butt burn (monkey butt) and your butt bones get sore. Feels like you're sitting on the seat pan. So the it all boils down to a combination of using the right kind of seat foam and shaping the seat properly so it evenly distributes the rider's weight over the surface of the seat.
Oh, and by the way, in that pic I posted of my Russell Daylong, it should be noted that when we had the seat made, we only had them do the rider's portion. The passenger's portion is covered to match the front, but inside is still stock. If you want them to make the seat so it fits your passenger, then they can do that too, with your passenger's information as to size, weight, inseam, etc. It would look quite different than the stock configuration in most cases.
