Helmet :smiley_th today was the difference between a ride in the meat wagon, and the ambulance. Slick oil/diesel covered by some dust (on the road), made me loose traction and wiped out. When i came off the bike had a couple of tumbles and a head (very top of helmet) hit with the the engine guard of another bike. Tried to stay holding bike, sliding to the left side of road to no avail. Was 124 miles away. Neck, back, and ribs bruised. Helmet can be replaced. Can not wait for ambulance and ER bill.
