My bud has a 2004 525 exc that has a California plate that I'm thinking of buying. I understood the previous cutoff for legalizing dirt bikes was 2003. Is there a loophole somewhere that allows this bike to be street legal or am I at risk of losing the plate if I buy it? I searched for an answer to this on Thumpertalk and could not, for the life of me, find it. I seem to recall that the VIN had something to do with it but can't find any post to that effect. Thanks in advance for any help someone might be.
