After Yam went with the Mag wheels and disc brakes front and rear they also sold a Special II model ('79 to '81 ish?) with wire wheels and chromed steel rims (rather than the previous flanged alloy rims) and a rear disc brake. My brother used to own one. Otherwise much the same bike. Wire wheels look good on a tracker, though I've also seen some nice mag wheel ones.
A Special II with a disc rear brake would be rare indeed.
