While I wish you luck for your "dream bike" to turn up, you're not going to get it. The 800GS is the adventure version (of the F650GS). You want more? Buy the G450X. BMW aren't an off-road manufacturer. The suspension they fit to the bike is, they think, a good balance of cost and capability. If riders don't like it (and no manufacturer in the entire history of all the planes of the multiverse that ever have been or will be, has ever built suspension that everyone universally likes), they can fit their own. BMW don't sell big numbers of bikes in the USA, they build for Europe, where the R1200GS and F650GS are kings of their respective categories. If there was money to be made in "Dakar" versions, the F650GS Dakar would still be on sale. It isn't, so you can assume there wasn't. If you genuinely and passionately believe there's a market for an Adventure version of the 800, pony up some venture capital and start a conversion business. I'd buy one. Until then, I'm happily riding.
