Damn near all the time. I don't trust the idiots in my area to go on the street without it. Also, bugs are annoying. Cleaning my bike is bad enough, I don't want to find bugs and debris while I'm washing my hair in the shower. :nono
Call me chickensh*t, I get squirrely going above 10 mph without it.
i would say about 85% of the time. i always wear it on the highway and on longer rides. i also mostly always wear it when riding at night. sometimes on the short rides i won't wear it. oddly enough, when i started riding, i had my lid on 100% of the time. i could have been running to the dominicks behind my house and i'd have it on.
for the most part, i wear it.:helmet
took me about 2 months before i got a good jacket, and i feel safer now, even though it pulls more air & jerks me around more than just skin. that link is the exact reason why our significant others don't like us going out without gear. i've seen too many wrecks to not wear my bucket, but if i'm driving to work, i'm an idiot and won't wear it. might mess up my hair!:confused
