About 35 years ago, I road rashed myself pretty nicely at very low speeds.
Christmas Eve, coming back from seeing a lady, was riding a tiny Honda twin, like a 200. Was around 1AM, was one house from my driveway. Was in second and slowing, blinker on. Had on leather jacket, decent helmet, leather riding boots, but wearing jeans.
A black German shepherd just appeared in front of me as I passed a small spruce bush in the neighbor's yard on my right...he apparently came out into the road from behind the bush just as I was passing it. Hit the dog square with the front wheel. Tossed me over the handlebars and I skid a bit to the curb.
Jacket and boots and gloves saved those parts...helmet had a few dings from hitting, too. But the jeans gave up immediately and I still have some scars on my right hip and knee.
Dog was trapped under the bike with the right exhaust pipe burning him. Neighbors came out, lifted the bike off him and he bolted, yelping the whole way. Bent the forks on the bike. Shame, really. It was a fun puddle jumper.
