That describes me and the MABDR exactly.
The MABDR is scenic with easy gravel and rural pavement roads. Probably >50% pavement. There are 2 short challenge sections that were not a problem on the DRZ with 17" Shinko 244s. My friends on GSAs had more of a challenge but only 1 minor off. Some of the gravel, especially in the north half was really fast. Plenty of nice camp grounds in the national and state forests and parks. It was fun and a good shake down for my camping and packing. The hundred mile range on the DRZ was sufficient, though I did have plan a few short detours for gas and never pass one marked on the tracks.
From what I have read the western BDRs are much more challenging. The nice thing is both the start and end of the MABDR is within a days ride of Ohio.
