Hi mate,
I have an SZR660 and the same issue if spending a long time in the saddle. The guys on the SZR forum seem to recommend drilling the top yoke and fitting clamps for raised bars - which I would do if I had easy access to getting it done. Of course if you do the bars, do you then do the pegs...........?
Mine is mostly used for short, rapid blats so I guess I'll cope. Although purchased panniers ready for Dent today so that might change things....
