I live in a part of the country where I don't consider running 40 in much of anything power sport wise. I have nothing to run this type oil in. I am curious about 0W40 though but, not necessarily Klotz.
Both Mobil 1 and Castrol make highly regarded, and much less expensive 0w40. As far as motorcycle application is concerned, the 0W does not mean much, unless you plan to start your bike in -35C conditions. Above -15C, a 0W and a 10W are by definition in the same viscosity range.
If you are talking about using this in a motorcycle with a wet clutch, you have to be careful that the oil does not contain friction modifiers....("Energy Conserving" in the circle that defines the specs of the oil are a bad thing for wet clutches.)
Then, since the oil would also be in the shared gear box, shearing out of grade (So that your 40 weight would soon be a 30 weight) and so on, can be an important issue.
Diesel oils are popular for use in shared sump motorcycles, with wet clutches. If you want a synthetic, Rotella T6 or Delo, either in 5W/40 are excellent choices. But many would argue that the conventional versions, Rotella T5 or Delo 15W/40 would shear less, in those gear boxes.
