According to the motorcycle dealers, yes. The additives are different. A test done by by John C. Woolum/ Ph.D.

California State University, Los Angeles shows that the testing of motorcycle oil against automotive oil shows no difference in favor of motorcycle oil. In fact the lowest score in viscosity were the motorcycle oils themselves. All of which were out performed by SG rated automotive oils. Source : http://www.nightrider.com/biketech/oiltest1.htm
one has to or three wheels and the other has four
Usually the recommended grade of oil is stamped on the oil fill cap, but it is similar to automobile oil. I use a 5w30 oil in my Suzuki.
Each manufacture uses a special blend of oil in their automobile shocks. Unless you are talking about the front tubes on a motorcycle you cannot replace the oil. Refer to your owners manual for the correct oil to use in a motorcycle.
Yes there is no difference. I would however recommend you use synthetic oil in a motorcycle especially an air cooled one.
Automotive oil is formulated as a engine crankcase oil and Motorcycle oil is formulated three jobs a crankcase oil, a transmission-gear oil, and a wet clutch oil.

The grade and viscosity of the oil
yes
A mechanic needs to know many things about cars and cycles such as automobile engines, how they run, other car parts, how to repair an automobile or motorcycle, and how to perform an oil change.
Many motorcycle owners are given conflicting information about what type of oil is required. While some manufacturers recommend the use of specially formulated motorcycle oils, it is perfectly safe to use automobile oil as long as it is of the proper viscosity.
There is not one. Harley Filters are made better than Fram Filters. You might consider Purolater motorcycle filters or a motorcycle filter made by Champion. Do not use an automobile filter on a motorcycle. They are made for oil pumps that have higher pressures. Try the Fram PH6065B
No difference
