BTW both of my bikes are 750cc. Pleanty big enough to pull leagal speeds (and above) around any hill here in Ca.
Funny thought about helmets. I did see a young lady riding on back. Flip flops, short shorts, tiny tank top, no gloves, but a full face helmet. I guess she figgured that when she fell off, she would just slide down the road on her head.
I have a "bomber" jacket, and I alwise wear long pants, shoes, and gloves when riding. I do use an open face helmet rather than the closed face. Mostly because I ride a lot, and I haven't been able to get a closed face helmet that has a "beak" like a cap. I like that to keep the sun out of my eyes for part of my commute.
