Shift linkage boss?
When did the airhead frames first get the boss to which the shifter linkage attaches? As opposed to the shifter that attaches directly to the shifter shaft on the gearbox...
I find pics of /5 and /6 bikes without it, and later bikes with it. But when did it first appear?
1974 R90/6 w/1050 kit
