Why not just mail everyone the sticker with replacement intructions? save$$
For California those stickers would have a large potential for misuse like I tried to indicate in a joking way above. This sticker is what is the main control on what bike is eligible for a plate here. It's the reference for the DMV. They look for those words indicating that the vehicle is on road smog tested. Checking on engine families is a bit beyond the average DMV drones skill set.
Dang, I don't even have smog test my cars.This is the pre-cursor to Smog Checks on motorcycles.
So am I...I so glad I don't live in commifornia.
