On the way to NAFO from Northern Cal. in '08, I stopped in at Bonneville, removed all the bags and made 3 runs across the salt. There was almost no wind that day, so direction had no effect. Speedo indicated just a hair under 155, though I don't have any idea the real speed. I do know that without any ditches, fence posts, or white lines to help keep your orientation, that speed feels real eerie. Outside of the sound of the engine and air, there was little indication of speed, except when I passed the occasional marker cones set out there in the July sun. The bike was rock-solid at that speed, which kinda surprised me. Each run was about 3 1/2 to 4 miles. There were no other vehicles on the lake bed. Took a while to wash off the salt when I got to Salt Lake City!
