I ride a 2002 Dyna SuperGlide Sport. I love it! Don't listen to the Harley bashers in Y!A. I admit, there was a time when they were not making very good bikes, but that is not the case today. Recent models are reliable and do not leak oil. No other bike sounds, feels or rides like one. They are true originals.
While many foreign made sport bikes can out run and out handle Harleys, they are very much the kings of cruisers and tourers. They can be infinitely customized. Virtually no two Harley's are the same.
If you walked out into a parking lot of 100 Harley's, you'll know right away which one is yours. If you walked into a parking lot of 100 sport bikes, you'd be there for a while trying to find yours.
There are several books you may find in your local library to read up on the rich history of Harley-Davidson and their impact on motorcycling in general. Knuckleheads, panheads, flatheads, evos, etc. Harleys in the military, fire and police bikes. Its endless.
Sounds like a great project. Good Luck and I hope you get an A!
