First Harley - Sportster - on a whim

I found out the "5" on the tank emblem is announcing the 5 speed transmission upraded from the previous 4 speed.

I'm researching protective gear now. I had thought I'd get a half or 3/4 helmet to go with the retro bike but after reading "Proficient Motorcyling" which has a lot of sobering crash stats, I'm inclined to go full face modular type. One benefit I see is I will be less likely to want a windshield. Also looking at other protective gear.
