Just got a used Corbin for my 09 1300GT. Firm it is, I'm not happy with the mounting details though. I realized that the two position of the stock front isn't there. I'd like some tall rubber cushions like the oem seat, just for comfort.
The pillion seat pretty much doesn't fit without some work. It appears I could just trim out some fairing / side panel bits to make it fit. Which I will not.
But the price was okay, no complaint there. I'd sure like a decent picture of what it should look like, (the mounting details of the rear seat).

Fortune favors the prepared.
