Re: 1000RR swingarm on a 954
I don't know because I haven't had my 929 arm off the bike for comparison but it certainly isn't light.
I assume it's particularly strong due to the 1000RR setup of both ends of the shock being attached to the swingarm rather than to the frame. All the swingarm loading is contained by the swingarm rather than distributed to the frame. I could probably weigh it for you if you can weigh a 929 or 954 swingarm for comparison.
