To remain under the size requirement from emission control equipment, the engine was reduced in size in 1969 to 817cc. New features were added to the Siata 300 BC that included locks, seatbelts and new seats with headrests. Updates were also made to the windscreen, brakes, rear lights, dashboard and instruments.
