I rode for two hours at 75mph on my wr250x, stock gearing. This is with speedo correction as well. On flat land there's still enough to hit 85 or so for passing. I'm 6'1" and 175 for reference.The one question that I really have is top speed. Is there a supermoto that can actually cruise at a minimum interstate speed? I didn't like cruising over about 55-60 tops on the DRZ. I'm just looking for something with a little more ompf on the top end to get it into that highway cruising territory without completely giving up the soul of a dirtbike. From my limited searching, seems like some flavor of KTM 690 might be better.
