There's a bit of info on the forum in the Search box.

Basically (imo) the standard Tenere suspension is rubbish. It's the first thing that needs doing, really. (I didn't, and wish I had).

If you're a confident sand rider, the Tenere should do the job, remembering that momentum is your friend! But I really believe a suspension upgrade, both ends, is a must, and if you're going to do it, it's best done properly especially the shock. Mine really wasn't good.
