You drilled one thing - the harley "style." As soon as most Harley guys get their bike, they spend a shitload of money buying clothes and gear to look the part. I cant explain why, my only guess is that its a lame attempt to fit in. The reputation Harley Davidson has achieved is that of the American biker bad-ass.
Going one further, I like the bikes. Custom choppers are even more appealing to me. Yet I catch all kinds of grief when I wear a harley shirt or West Coast Choppers shirt. Most likely because I do not look the part, or I am wearing one while on my sportbike. Big fucking deal. I like all bikes, not just what I ride. This irritates the shit out of me, just because I dont own one or ride one means I cant wear a shirt? I cant wait until the day when I have a nice chopper so I can wave to sportbikers.
I actually have several friends that had to get all the gear as soon as they bought their Harleys. Even when not riding, they wear the standard bandanna, boots, and Harley shirt. When questioned about it, they just laugh it off.
About the boots:
I would much rather wear boots and gloves (with no helmet) and die with pretty hands and feet than wear only a helmet, survive a crash, and have to live the rest of my life walking on krutches/one handed/wheelchair/whatever, just because our hands and our feet are such huge contributors to what we do every day. Something to think about.
