except for a mate of mine on a bike overcooking it a bit + moisture on the road, into about the third corner of kangaroo valley (which was the first lot of twistys we got to...) and unfortunately slid into a concrete barrier.
He was fine luckily but the bikes abit of a mess.. and fortunately we had two utes with us on the cruise so we just heaved the bike into the back tray and carried on lol.
