Massimo MB200 Parts Catalog. We recently added Massimo MB200 parts, because like every Chinese motorsports unit out there, people have a hard time coming up with factory parts for these guys. We buy directly from the factory in China... the same factory that produced the Baja MB200 mini bike years ago. A lot of the Massimo MB200 parts also fit the Baja MB165 and MB200. Do you need your Massimo MB200 parts fast? If you order before 3:00 pm CST, Monday thru Friday, your order goes out the same day. Free shipping on orders in USA over $100. Excludes Hawaii and Alaska.
