1. Make sure the BIKE isn't a LOW OEM bike...unless you want one. Just sayin'
2. Swapping seats? Take off the LOW...put on the STANDARD. Done.
No dealer involvement needed.
BTW...I changed my STANDARD GS seat for a STANDARD GSA seat...first ride yesterday...GSA seat is MUCH MORE comfortable than the GS seat.
GSA raises the ride height about 1" IIRC. More gel? in the rider seat.
You should be able to use the GSA seat, as well, unless "height challenged".
