Have you removed the wheel? Just to make sure the spacer is still there. There has been quite a few riders of them K1200RSs that have experimented with removing that spacer to correct their tendency of pulling to the right.
Wouldn't be me doing such things, I have the 5.5 wheel, not much room between the tire/swingarm and I know that a tire may change shape at speed....just enough to rub the swingarm.
But....I'd go with some of the earlier post,just because that bike has been repainted, they never came in white from the factory.
