OK, so for starters, I am sticking with School, as opposed to Skool or Skuhl. Guess I am a fan of the Queens English.
For the purposes of this site let's consider Old School, as air cooled (and oil boilers), 750 cc and up, 4 cylinder and 4 stroke.
And before you write in...yep, twins can be old school too, and smaller capacity. Just not here...
For me the ultimate in old school is the final, finest, phase - 1983.
The year after this, 1984, Kawasaki released the GPZ900R, lighter than the 1100, almost comparable power, better handling, and water cooled. Motorcycling pursued a new path thereafter.
But in '83 we had the mighty ZX1100A1, 147 kg of old school steel, 2 valves per cylinder, oil cooler assisted, and 120 horsepower.
So what is it like to own one of these relics?
Well there are oil changes...
But you can always find a friend to park near. Big air cooled Kawasaki's are like a test, if you ride one you have passed.
