Hi All first post here. I have some questions about green plates and blue plate........this is all new to me,so bare with me. Can I say, buy an an old KLX300 or whatever and plate it?......would that be a green plate? Can you drive on the road with a green plate or are they just for trails? Now, Blue plates are no longer issued? and if I bought a bike that could be blue plated....what is the difference between the two plates.
