I "wick it up" (from an actual 70mph) to pass convoys of truckers on two lane deserted highways(I-80 in PA) - mostly to minimize the wind buffeting (the square faced trucks are the worst as they leave a wake about 100 yards long and fairly severe as you pass the drivers cab). This past weekend, I passed five trucks (no one else on the highway) and when I passed the last one I was at 110 on the speedometer which is about 105 I imagine.
No wobbling, no headshake, the bike actually felt like a steady rocket compared to passing those same trucks at 70 real mph.
MPG - 48 from CT to OH and 51 from OH to CT, measured at the tank for the 650 mile trip west and 650 mile trip east. I believe the West to East tailwind helped the mileage on the return trip to CT.
