For me, doing limited off road on my DR, I would try a 45T rear and then swap out front sprockets as needed. Seems with a 14/45 combo you'd have decent low gearing to putter along at fairly slow speeds without having to slip the clutch too much.
Then, if you wanted to go back on road, swap to the 16T ... which gets you back to stock gearing ratio.
If someone has found a 13T front sproc. that fits the DR650, I'd like to hear about it ... and I wonder how it worked.
FatChance did a very nice write up on gearing for the DR. He uses a 48T Rear and switches between 14, 15, and 16 in front, but he has to add a few links to his chain to do it. I think he also said that the stock chain was too short for a 15 or 16 front and the 45 rear. Here's his write up:
