Ok, I have some numbers here.
Just got a reply from Patrick. The front wheel (848 wheel) is 6.9 lbs with the bearings installed, and the rear wheel is 8.8 lbs for a combined total weight of 15.7 lbs.
Look at me practicing my maths here!

Good to know. I had my rear wheel off already so I was curious and put it on the scale. 23.0 lbs exactly. This is with the tire of course. The published weight of the 180/55 Pirelli Diablo Rosso is 13.8 lbs. So the stock rear 796/1100 SSS wheel is ~ 9.2 lbs
