And it is not just bikes:

I had an aftermarket roof rack on my Jeep 4WD ... fail ... roo-bar on the front ... fail ... Jeep stickers in the window ... fail, and so on. So, there is a large industry of returning your car/bike to original ... pass the test ... and then put the farkle back on. These helpful shops can be found next door to the testing stations.
Unless there was significant changes in rules, it was two times two years and then annually for the inspection. My bike was for the annual test three days ago, with panniers, top case, cameras , additional stickers, ... and it passed. The only remark they had - the horn is too loud. Yep that is what a Nautilus should be
