Expect to find potholes, sand, speed bumps, livestock, pedestrians, etc. Some highways have heavy traffic, remember that most everything moves by truck or bus. In addition, there aren't nearly as many motorcycles in Mexico as the US, so drivers won't expect them. All of that increases the risk. On the other hand, most of the autopistas that I've traveled have had relatively light traffic.
Many rural roads have similar usage.
So, it depends a bit on where you'll ride. I decided that there were many things more important to me than my bike. Like walking, for instance. I miss my bike. I owned several and lost a few minor body parts here and there.
