Would someone with calipers and a 2007 Z1000 please post the diameter of the upper forks, the gold anodized fixed tubes not the lower sliding tubes? Thanks.

That can't be. The upper tubes are bigger. You must mean 52 upper and 50 lower.

But I have a big adjustable wrench that almost but not quite fits over the upper tubes. When I measure the wrench jaws' opening with a desk ruler marked in MMs, it's almost 48. So ... :thud:
