I had a long drawn out registration process when I moved to Aridzona .
If you bring a vehicle from out of state, it needs an inspection before a new Aridzona title and license plate are issued .
At least on the US bikes, the only place the entire VIN is located, is a foil sticker on the right side of the frame, below the right cylinder .
The numbers on the sticker on my bike were not fully legible .
I learned through a coworker that also rode BMW's, that at one of the inspection stations one of the inspectors was a BMW motorcycle enthusiast and fully understood that after 20 some years, the stickers are not very legible, went to that inspection station and I had everything done in an hour !!!!!!!
If I remember correctly, two of our members here MrRiden and Mike V, had similar issues when first getting their bikes registered in Aridzona and California.
