I have been enlightened
Buddy has a couple of DR650s and invited me to go riding.
Wow. So much torque. Cruised highway no problem. And the best part... really not too heavy. You'd think that something with significantly more torque than the smaller dual sports would be significantly heavier, but it's really not. Maybe I'll feel it once I hit dirt more, but I'll keep my KLX 230 in the stable for those times.
It's crazy that it feels like Suzuki perfected the dual sport 30 years ago. I can't imagine any other bike serving its purpose any better.
He let me ride both of his; one was on aggressive knobbies and the other was on road-biased 70/30s. The one on knobbies felt unresponsive, like it wandered around the road. The road-biased one felt incredibly precise. Do tires really make that much of a difference? This explains so much...
