I am looking at taking advantage of off season prices and pick up a used bike. It's been a number of years (okay 35) since I rode regularly. I have spent the last couple of months putting my grandfather's 1972 Harley Electraglide back on the road, but I am pretty sure I want something at least a tad more nimble and better suited to getting onto the forest service roads.

Ease of maintenance (working on the harley is simple and I like that), highway and forest service capable, aftermarket support and to a lesser degree fuel economy are the filters I used for my search.

I have what I think is a pretty good "short list" but I have never touched let alone ridden any of the bikes on the list. I am somewhat flexible but the target budget is $4k. Which brings me to the questions:
1) are any of the bikes a bad enough choice to be stricken from the list without further research?
2) does anyone have one of the bikes in question they would let me kick the tires on and possibly ride. I would gladly pay for the fuel and beers afterwards ( I took the MCSF riders course and have the endorsement on my license)

The "short list" in alphabetical order
DR650S
KLR-650
