My GS 1200 - 'round the world bike', has fallen to the incredibly unreliable servo assisted/abs system - replacement/repiar around £2000. Out of my budget, my solution is to take the bike to the non-abs version - bike available in both abs/non abs models.
There are kits to bypass the unit as far as brake pipes, canbus causes issues with electrics.
I am not sure where I would stand with insurance, any advice would be gratefully received.
I find it hard to believe that BMW have fitted such unit, (Replaced with non-servo system in later models) non repairable and so expensive to replace.
