Adventure motorcycle searches in the US cluster around BMW GS, Honda Africa Twin, Yamaha Ténéré 700, KTM 890/1290 Adventure, and CFMOTO 450/800 MT. The split that matters is weight: a Ténéré 700 or 890 Adventure is a dirt-capable street bike. An R 1300 GS is a highway tool that can do a graded road.
Most US “ADV” miles are pavement, then Forest Service and BLM roads. Deep sand and technical singletrack belong on a dual-sport 250–500 or a true enduro with a plate. Luggage, crash bars, and a skid plate matter more than extra horsepower once you leave the interstate.
Seat height is the US buyer filter. A 34-inch seat with luggage is a different bike than the brochure photo. Test with boots you actually ride in. Middleweights are easier to load into a truck and to pick up on a rut.
Shop used Africa Twin and Ténéré inventory before you finance a new 1300. Service intervals and dealer distance in the Mountain West are part of the purchase, not an afterthought.
