I only hear good things about the Seat Concept seats, sadly living so far from the USA makes nearly impossible to get it here in Bolivia. Great video Offroadxplorer!
I met the guys from Seat Concepts almost ten years ago. Great bunch of guys. Send them an email and they may be able to help you and ship to you what you need.
Read the fine print. Once they have your money, don't expect your seat for a couple months. Maybe your fortunate to have a longer riding season.
Perhaps you're right. Seat Concepts have a huge range of seats which are all handmade. Production runs of foam elements and the availability of seat pans from OEM manufacturers can cause delays. However, distributors such as Adventure Moto in Australia will order the seat and you don't have to pay until the seat arrives.
Seat pan... Are you kidding? For $260 dollars you get a cover that you have to install on your existing OEM seat.
