A further update on the issue of the Maxton T260C shock possibly fouling the rear rack. Having done a bit more research it appears that only the Givi SR8201 and Kappa KR8201 (identical) use the rear footpeg mount and so have a tube that passes behind the shock just below the top eye. Other racks seem to utilise the top eye mount with a longer bolt and so don't encroach on the shock itself. There may still be issues with side cases/bags of which I am unaware as I have no experience of these.
