My brother rides a DRZ 400 off road, but doesn’t ride street. He loves his bike but I would be aware of a few things, as I have ridden it as well:
1. You’re going to be shifting a lot
2. Usually dual sports have a seat height that is considerably higher than other bikes . I’m 6′ even, and I’m on my toes with the DRZ. This means a higher center of gravity, which is not always beginner friendly.
3. The seat is built for the dirt, not the street. It’s designed more for a temporary rest between running over bumps
On the other hand, one of my friend’s only mode of transportation is a KLX 250. I recommend getting at least a 400, because he had to practically rebuild the engine to get the power he wanted, and he wasn’t too happy about it. However, he rides it every day, he’s shorter than me, and a lot more picky about things like comfort..but he has no complaints about his dual sport other than the low power.
Guess I would recommend sitting on one, that would tell you a lot.
