If you look at the Vader 125 which is made or imported by Baodaio/Boom! International, on the Powersportsmax site, it has the same states listed as not being allowed to purchase that bike, and also states the Vader is Cal. green sticker. In the listing for this bike, it mentions the engine model as being a BDXXXXX, so I am guessing it is imported and sold by Baodaio who import and sell the Vader. That is just my guess, and this bike is not on their website.
