Rim locks are a must! I do not know why KTM made a bike without them. If you have a flat the wheel will just spin in the tire. After install them balance the wheels. Mount them opposite the valve stem.
Due to this fact the lightest tire position is marked with one or two red dots. The red dot marked position has to be mounted at the rim lock. The dot is the lightest point of the rubber.
It is easy to say you will ride on a flat, but it is NOT easy to do. The tire will flip from one side of the rim to the other. I had a flat on the front on a dual sport run & rode out to the support truck. I would be in the woods on the right, then in the woods on the left, then flip, repeat about 50 times in a half mile. Another time I had to finish an enduro on a flat with the same result. It is quicker & easier to stop & put in a tube.
You should practice tire changer at home several times. Here is a tire change video from Dirt Rider.

It is very important to keep the bead you are working with in the valley opposite your work area. That way the rim is smaller than the inside of the tire. I like that he did not put the valve stem nut back on. If it is installed & the tire goes flat, it can rip the stem out of the tube.
