In fact, the motorcycle (I am informed it is something produced long ago by some defunct manufacturer, and thus, in pursuance of the study requirements, utterly irrelevant, is in fact a "stock" motorcycle, which we are informed means a motorcycle such as one could purchase, when it was in fact offered for commercial sale, by any member of the purchasing public who, for whatever reason (we offer no conjecture) should happen to wish to do so).
What IS new in the picture presented for observation is the air conditioning unit shown in the window observable in said picture, which was NOT, in fact, installed in said window prior to the date of the photograph presented.

Thank you very much, and good night.
