Also consider a DR650.
The KLR is ready to go ,with a big tank and a fairly comfy seat .
The DRZ will need a bigger tank and a better seat .
THe DR650 will also need a bigger tank and a decent seat .
I,ve been very impressed with my son's DRZ [and he has done a few long trips on it ].It's a good reliable bike ,more suited to the younger guy who wants to do rougher terrain.
Try them all out before you decide .
KLR will probably be cheaper ,but be careful you don't buy an old clunker .
