Yes, I have ridden with no gear. Yes, I would ride differently without it, but saying that makes you safer, requiring less gear is a red herring argument. You may be less likely to have an accident, but its more likely your injuries will be more severe My last get-off about 10 years ago was a freak low speed high side on a straight.section of road where antifreeze had been spilled on a fresh tar strip while riding a V-Star 650 classic. Besides the ff helmet, I was only wearing work gloves, hiking boots, and an insulated rain suit over work clothes. I landed head first and was knocked unconscious, being low speed I didn't slide, so no roadrash or other injuries. Judging by the dent and cracks in the shell of my helmet, I have no doubt it would have been a fatal blow to the forehead if I had not been wearing helmet. It was so unexpected and conditions so benign I can honestly say I wouldn't have done anything differently if I hadn't been wearing any gear. IMO, the only honest justification for wearing no gear is you accept the increased risk of injury in a crash.
