Just came back from a weekend trip through part of the Namib and part of the Kalahari. Loaded with camping gear, varying road conditions including sand and a short bit of tar. Cruising speed was 120-140 on the gravel. The GSA was perfect, I am keeping the battleship!
I also had a quick ride on a lightly loaded Tenere. Was very impressed with the suspension and how nimble it felt, but the GSA stay my weapon of choice. If one start to look at mid sized bikes, I believe that Tenere will be awesome.
