I would consider above an expedition, and not a tour. If you cannot call yourself a tourist, then it's not a tour.

If your goal is to cross a country in as short a period of time as possible, then what you've listed will work.
Above is what I consider an essential element in cyclo touring, to a degree, with the joy of cycling thrown in. That means traveling reasonably light, and travel fast. I like to visit places of interest, meet and talk with local people, and eat local food. Yet i carry some dry food, in case I get caught by some unexpected event, tent and sleeping bag when local accommodation cannot be found. So, essentially, I tour and cycle. I don't like camping with bicycle. I go camping with my family with car.
