That's the right riser for the bike. Just make sure you can get a brake line made before you get all jiggy. The stock brake line will work on a 1200GS, as Rox says in the ad, but will not work on the F800R. Sargent seats are pretty good seats for an aftermarket seat, but you will pay about the same amount of money for a superior custom seat. Check out Rich's Custom Seats. He does a gel seat that IMHO is waaay better than regular aftermarket seats, with gel and leather about $550. I got a quote from KnoPlace for $200 for gel and leather. For $200 I'm definitely going to try them out.
