People make a big deal about the differences between the KLR and DR, but compared to other machines out there the differences are small. Neither are 250 motocross bike. Neither are a huge tourer disguised as a dual purpose bike (eg GS-ADV, S-Tenere). The key is how much bike you can pick up, even when loaded with gear. If you're taking it off of gravel you will eventually drop it.
The nice thing about the DR and 1st gen KLR is the plastic is the same stuff they make laundry baskets out of, so it usually flexes and scrapes instead of shatters.
