I would suggest that you contact the local SF office of the US Dept of State, and/or AAA for any travel advisories. There was a news item on GMA this morning [2/11] wherein the State Dept issued a cautionary travel notice for various parts of Mexico due to the ever-increasing drug cartel violence. It was pointed in that the strong recommendation was for those that do go, to stay withing the resort complex.
Since you anticipate a long {solo?] ride down the Baja peninsula you will be at the whim of whom ever drives by.
I am not suggesting that you don't ride it. Just be fully aware of what you might be facing.
YMMV
