One has to give the Corbin some time. My first was a Corbin Canyon on my 1976 BMW R90/6 and after the first ride I thought I could have have purchased a 2""x8 board for less money. As I continued to ride though it became very comfortable with no hot spots, and hot spots are one of key causes of soreness. Corbin and other manufacturers of aftermarket seats use higher grade foams. Below is from an on line article I wrote years ago.
"Since then I’ve visited and toured 4 different seat builder facilities, asking a lot of questions about design, material, foam type, styles, etc. It was all very enlightening and while each had similarities there were also some significant differences. Over the years I’ve visited Corbin (twice), Rick Mayer, Russel, Rich’s and a local Seattle custom seat builder who Rich used to work for.
I initially wondered why such a nice cushy and seemingly well designed seat could hurt so darn much after only 80 miles. The answer was primarily due to hot spots and compression of the old butt housing group. Although something called Total Vertical Motion (TVM) is also a significant factor, that is, how much the seat allows the rider to sink down into it. TVM also impacts the rider’s ability to move in the seat during aggressive twisties riding, and thus the ergonomics of the seating position.
Each seat manufacturer told me the same thing, that production grade foams used in stock seats can result in what one moto-journalist referred to has the 80 mile foot peg dance. We’ve all done it. When riding my new Triumph Rocket 3 home in 2007 from Florida to Washington state I was in agony by the time I got to Chicago and felt that I would not be able to press on unless I did something about it. The temporary fix was an Airhawk pad that Titletown Cycles in Green Bay ordered for me. How do you spell relief? Airhawk.
I learned that some of the foam types used in MC seats are, open cell rebound foam, closed cell foams which includes polyethylene and mini-cell, closed cell neoprene (kind of a spongey rubber), open cell polyurethane (comes in many different densities) and of course gels and memory foams. One will also hear the term “dual density” when describing foams but more often foam densities are measured in pounds. "
