My 1150GS passed its MOT on Wednesday but with the advisory that the rear shock is on its way out (not too bad for 56k miles). I've looked through lots of threads on after market replacements but haven't decided on which one to go for. One thing that does occur to me is if I replace the rear is it worth replacing the front at the same time as a matched pair or will a new rear work fine with an OE front ???

though I'm also thinking about a 'pre-loved' OE set
