i have the same prob with my kwak zrx1200,

if you let go of te bars it goes nuts, but even the lightest touch on them and it stops, ive had the head bearings, wheel bearings checked and theyre fine, had it rebalanced still no different, apparently some tyres just do this, im on mich pilot road 2's, otherwise excellent tyres, never had same prob with any other tyres, and chances are when i swap them agin for the same i wont have probs again, i was told that sometimes just a slight uneveness in the wear on each side can make them out a fraction, and thats all it takes,

so the top tip of the day is ,,,,,dont let go of the bars........................
