Hi Graig, I will check to see if the dealer can still get them. If so I will provide the info. I got mine last year, a few months after receiving my GT9. The comfort seat is better than the one it comes with but not OMG better (my opinion). As soon as the weather permits and will restart putting the miles (km) on it and we will see. Plan B, if I’m still not satisfied, I will modify the original seat myself and add quality foam and shape it to fit my need. Something else to consider depending on your preference is the incline of the seat. A couple of days ago I installed a kit from https://jk3d.us/. It’s a smart low-cost shim kit.

It does the job but the fuel tank needs to come up a little more than the stock position (2mm). It works but being picky and meticulous, I did a few other small mods to make it look and perform better. I can provide pics and details later if anyone is interested.
