What you can try is .... remove the wheel ... use a 10mm socket and preferably some kind of electric , or battery powered or pneumatic impact (to get a ratcheting effect) , and try to remove the entire bolt ... going at it with the wheel removed gives you direct straight access to the bolt and it should make it easier to remove and means you can use a 6 point socket so as to help prevent stripping the bolt head ...... I am thinking if you break the entire bolt loose then it should come free .... if not , they do make a repair kit if the threads inside the swingarm become damaged , but usually the impact will allow the entire bolt to be removed , then you can either replace them with another , or attempt to salvage the bolt and just replace the nut from a hardware store .....
