New to me Corbin Seat

[Stichill]

The Corbin proposal is that factory seats are designed to feel nice and cushy on the showroom floor, and maybe for a 20-minute demo ride. However, out on the road, the factory foam is too soft. It crushes down under prolonged use, until your butt bones (ischial tuberosity) are pressing against the hard metal seat pan under the foam.

Corbin counters this effect by using a higher-durometer (harder) foam.

Personally, I love the Corbin on my CBR250R. I can ride for long periods without discomfort. I was in misery on a week-long tour when I had the stock seat.
