Sargent is coming next summer: http://www.sargentcycle.com/Seats-Ac...-African-Twin/
The seat of Africa Twin is not bad, it's one of the best OEM seats of adventure bikes. In my mind just the KTM 1290 SA seat fits better to my a*. I really loved the heated Sargent seat on my former GS. Next summer will show, if that's also needed to Africa Twin.
