I just fitted a Delkevic exhaust and it looks like the exhaust side pannier rail could now be moved in at least 4 inches, this would still leave at least 1 inch clearance to allow for the heat from the exhaust as far as I can figure,have to ask a mate who is good at metalwork if this Givi rack could be modified,
It would narrow the bike a lot, I agree though,a decent size tank bag,seat bag and top box are great for short solo trips, I very rarely take a pillion anyway.
