tach and speedo

Can anyone tell me what year this tach and speedo are from.

one more try.

Well, I know in 1980 they started using "80 mph" speedos so it's pre '80.

They are standard looking instruments used from about 1976-1979, but the unusual 8000rpm redline rules out KZ650,900,1000 from the possibles so my guess would be KZ750 twin. Anyone here confirm 8000rpm redline on that model as I have no idea? I doubt smaller than 750 because of the 140mph speedo.

Gauges on my 79 750 twin are 140mph speedo, and a ~7800 RPM redline on the tach. Those look pretty close, but I cannot tell how many lights in the middle - 4 perhaps? (Neutral/high beam/oil/stop lamp).

And how are you guys reading the redline on the tiny pics? :blink: Am I gettin THAT old? :pinch:

there are a few kz750 tachs on ebay. some have a 8000 redline:
