The DR is basically just a big trail bike. You've stated that most of your riding is on the road though.
The KLR comes with a much more sensible fuel tank... 22 litres. The DR's tank is only 13 litres, although there are plenty of after-market alternatives.
Seat height is about the same... DR = 880mm, KLR = 890mm.
The KLR is 22kgs heavier, but that's only an issue offroad.
The KLR's seat is more comfortable. So, it's a winner if you plan long hours in the saddle. The DR's seat is only slightly better than those found on enduro bikes, but once again there are after-market alternatives.
Both bikes have fairly simple no-frills suspension. If I was riding either of them on the road often, I'd be looking at stiffening them up. The DR in particular is sprung quite softly. However, at only 75kgs, they might be OK for you.
Both bikes have been around for ages and are mechanically similar. I wouldn't expect one to be better than the other in this regard.
So, for a mostly road bike, I'd recommend the KLR. If you had said that you planned to spend most of your time offroad, I would have recommended the DR hands down.
If you're not planning to do any offroad at all, I wouldn't recommend either bike - unless cost is a major consideration.
Hope some of that helps.
