Year before last I was riding with a mate (both on 1098's) his chain came back along the road towards me like sidewinding rattlesnake. It made a small hole in a casing on the way out, not too bad I was able to repair it easily enough. Not much room for a chain saver on either 1098 or 1199 and it wouldn't have been any use to my mate in any case, as it holed his casing to the side of the sprocket.
About 25 odd years ago another mate had a chain snap on his Honda 400four, no casing damage, but the chain managed to wrap itself around his pillion's foot. Nasty, she was barefoot except for a pair of beach flip flop's, again it could have been worse, she made full recovery just a couple of gnarly scars.
