The trip was 925 miles one-way. Lots of vibration on the pegs (mid pegs, not forward) caused some foot numbness. Traversing the desert around Barstow to Baker was very dry and necessitated a break for water. On a bike, you experience all the odors in the air that rarely work their way inside a closed car or truck cab. Some are nice, many are not. The temperature swings are significant too. 116 degrees coming through Baker. 42 degrees entering southern Idaho.
My Kawasaki Versys is rated to top out at 128 MPH. The Yamaha Roadliner is rated for 142 MPH. Track speeds. I would never do that on a public road.
In 1990 I rode an 81 Shovelhead Fatbob to Calif and back from Utah. It was 106F most of the way from Victorville to Mesquite on the way back. I drank a whole gallon of Gatorade and never needed a pee stop. I did stop a couple of times and drenched my levis on the way. That was when gas stations still provided air and water. They dried out in about 10 minutes. Lol.
