I did not try to build a motor bike that would be allowed on the roads, but for art mobile covered, and also used as Off Highway Vehicle (OHV) approved (trail riding). I have not finished the art cover, but later for that.
It may be that OHV registration from my CA state DMV is easier than on road motorized bike.
I just got all the documents: title, OHV reg, and sticker to allow trail riding on designated county, state, and federal lands.
A lot of people here though like the use of transportation and OHV is not that I understand, but fun anyway.
