I just bought the bike and I went through the dmv and it only failed because we could not find the vin number. Is there anywhere else besides the front sides of the frame I can find the vin because it seems to be not existent there. Also my tires are technically street legal but I would like some cruisers for longer distances. I know little to nothing about this stuff as of now so id like to get one set for on road and one set for off so I'm open to any gearing recommendations/ tire brand someone can suggest. Thanks for the help!
