And the best brakes by far of any bike of the era. I reckon the relatively small valves and consequent high intake charge speed have something to do with their performance, but I think it is cam design.
The torque peak of my old 1000cc T3 was at 3800 rpm, and that of a same year 1000 BMW was 2200. So the Guzzi is more comfortable and much more economic at high speed...and more responsive too, you can accelerate from 75 or 80 without a bunch of down shifting.
Now I am envious and wish I had a Monza.
