In 79 they had 3 models. The standard, a special and a special II.
The standard had spoke wheels, drum brakes on the rear, side hinge seat.
The Special had mags with disc brake rear, seat tipped up from the rear and lifted off.
The Special II was a combonation of parts from the standard and special.
They did this for a couple years. This phenomenum confuses lots of people.
Kinda like they had extra parts left over after making the standards and Specials, put the parts together and called it a Special II
