              Silly question perhaps but what would the benefit of a larger rear wheel be over the stock 17". I understand what happens with the front but not the rear (and presumably you'd need a speedo healer as well?) 
             
 |  Primarily more choice of tyres (as someone else said) - particularly knobblies... 
        
         I still don't have my maths head on, but a larger wheel will turn slower, so I imagine the (standard) over-reading speedo will actually be more accurate with the larger rear wheel?
