mine does this if you take hands off the bars and only if the topbox is fitted....take it off no headshakesHello, just wonder if you have the bars shake at about 40mph? quite a violent shake
then it goes when you speed up?...i think maybe its rear suspension too stiff?
checked head bearings seem ok, seems to eat front tyres too, got those metzler tyres
on pretty soft wonder if they are shit? this will be xmas bike fixing you see ,its been like it a while so now is time to sort it
