What a drag! Sorry to hear about your issues with the DMV. Colorado where I live is a piece of cake when it comes to plating dirt bikes. We are still supposed to have OHV stickers (even with a plate). Seems the state enjoys the revenue generated by the license plates and stickers...

2001 Honda CR250 (out of state riding buddy's bike stored in CO for his annual epic ride) fills my need for the occasional 2 stroke hit!
