Re: 929 wheels vs 1000rr wheels - weight difference?
they do fit, supposed to be just a tiny bit lighter. I can't tell you if its noticeable when picking them up because the 1000RR rims had some dunlops on them and I put Pirellis on and my 929 rims have Michelins on them. So even if I could feel a difference it could be in weight of the tire also. And on the bike I didn't notice any difference.
I have a spare 929 rear wheel that you can buy off me if you want. $125+shipping. It cost me $90 to have it repaired and straightened by Will's Rim Repair. Its orange with a polished lip (that could use polishing again as its not too shiny)
if you can't convince them, confuse them.
