I've heard that CA bikes after '04 model are the ones that get plates revoked, only place I've heard of that. I'm in highly fascist MA and haven't had any problems. Though I did have to buy a bike that was plated in a state where it can be done. Mine was plated in Montana and made its way to MA, to my good fortune. Many other states allow you to plate dirt bikes too. About half the XR650R's I see for sale are advertised as street legal, and most of those have the Baja Designs Dual Sport Kit, which is a good kit. Although if night riding, lighting and stator upgrade recommended. EDIT: Anyway, why I like the bike so much, only 300 lbs, liquid cooled, beefy aluminum frame, desert racing champ level suspension, no heavy electric start. BTW it has two (auto&manual) decompression systems, that make it very easy to start, I often start mine in slippers while sitting on the seat, it's that easy to kick over.
