I have every sympathy with the OP.
He has a 1200 Twipple Bwack. That magnifies the pain. Just imagine, the panniers could have been attached to a vanilla 1200 GS, in which case it would have just been bad but not life threatening. A Twiipple Bwack on the other hand is, well, I hardly know the words to describe it. The only thing worse (other than a paper cut, the most painful thing on earth) is have it happening to an 'Anniversay Edition', the physical and mental anguish from which is beyond imagination.
I would like to apologise to the OP on behalf of all brother bikers. I feel your pain. Ride safe, ride proud and above all..... Get off your high and over sensitive horse, stur your fat arse into action and trim yer fecking hedge!
