Looks to be a tax/tariff $ generator. I pity the fool that rides around on a motorcycle that isn't maintained. I know in NY it is a requirement, not in Florida. I have seen some real rat bikes roll through the shop only to be refused due to overall condition/possible liability issues.
Looks like a state inspection which we do have here.
When I was in Florida they did have the emissions testing but not an annual inspection, however I believe they had the ability to inspect the vehicle at any time when pulled over and write violations. Floridians correct me if I am wrong.
Newman I was stationed in England for 6 years and hated getting an MOT inspection every year. I remember when my 2 year old car failed the exhaust portion of the test due to a Borla exhaust system I had put on it. I had to go back home and re-install the stock exhaust, then go back for the inspection. Of course, I put the Borla back on right after I got my certificate and tax disc renewed. I now live (and plan to retire) in GA where there is no inspection what so ever. Some states do not require an inspection some do.
In Pennsylvania we have annual state inspection...focus is tires, brakes, lights & signals. All have to meet minimums, tires have a minimum tread depth, brake pads a minimum thickness, and lights & signals need to function.
