when i bought my 1st big bike in 99, i bought an r1 off a guy who had a bad reputation & the number plates were very well known as i found out after the 1st week when i was riding to my mates house...i had 6 highway patrol cars on my tail for 10min, rode to my mates house & they all jumped out & surrounded me, until i took my helmet off they calmed down off & strongly suggested "change your plates otherwise you will be pulled up every time"
i thought i bought a hot bike...geez!
moral of the story, the new plate worked for 5yrs
