The 1090 Adventure R is a VERY capable ADV bike and is 456 pounds dry. The 790 is only 39 pounds less. With 5 gallons of fuel, your talking 450 pounds vs. 490 pounds which really isn't that much of a difference and is kind of disappointing to me. I kind of wish they had stripped some of the bells and whistles off and made it about 375 pounds.

Even so....... 40 pounds is still 40 pounds and when you consider the range on the 1090 is about 220 miles with a 6.1 gallon tank and the range on the more efficient 790 is reported at 280 miles with a 5.3 gallon tank, you'll likely be leaving for the gas station on the 1090 even heavier and it won't go as far.

If you want to travel some distance on the road and then tackle some harder trails when you arrive, I'm thinking the 1090R is still the better choice as it's just a bit bigger and will do just a bit better on the highway. But....for shorter amounts of highway and large doses of trail and dirt, the 790 would definitely be my choice.

Having said that, cruise control, lean angle ABS and tubeless tires are on the 790 and aren't on the 1090. Those are some pretty nice things to have on a "distance" ADV bike.

Oh...and the 790 R is $1500 less than the 1090 R and about $8K less than the BMW 850 GS Adventure so a "decent" value for a pretty high performing bike.
