I have been using 93 almost from the beginning, in all my bikes. I noticed the CB1100 pinging on several occasions under hard throttle. I do it simply because even if the bike is designed to run under normal conditions just fine on 87, when one rides hard or under more extreme conditions of heat, it's a bit of insurance. It's often hot where I live and I like to ride hard. Also I always use 10W40 oil, 15W50 in the F800GS.
