The 650 Dakar is a great bike. One of our riding group has one.. As a 20+ year BMW rider, I enjoy picking on him, telling him that REAL BMW's have 2 cylinders and a drive shaft..
As far as the snob factor, it's not like it used to be.. BMW makes so many different bikes now that I can't keep up, but since I ride a REAL BMW, I don't care to keep up anyway..
I think the only issue that the Dakars had was a surging issue that required re-mapping of the fuel injection. Most were covered under warranty and those that weren't re-mapped didn't have an issue. Fuel mileage is even better than the KLR's.
Maintaining is a bit more expensive, depending if you do it or have a dealer do it, if there's a dealer around you. In my case, I've done my own for years, and since I've got almost 100 miles to go to any dealer, I'll continue to do my own.
If you buy the Dakar for the right price, you'll find it will retain it's value much better than the KLR. For some reason nobody looks at a 50,000 mile Dakar as out of the ordinary, but a KLR with that mileage is looked at as worn out.. As we all know, this isn't the case, but the market will still think it's a tired old bike..
If you decide to go with the Dakar, just remember... Pinky out when drinking tea..
