So eventually got round to fitting the steel rear subframe along with an XL XTank from Erik at Hot Rod Welding
This will give around 19 litres of fuel in total so about a 200-250 mile range
Hepco & Becker Pannier rails on RHS had to be modified to move them out by about 50mm so they didn't foul the XTank
Also fitted a lower front mudguard from an F800GS
Just need to get the modified pannier brackets shot blasted and powder coated
Going to use soft luggage so haven't bothered removing the extra support on the RHS frame which had been added to support the Acerbis additional fuel tank
