Not sure if this could be a problem or not but like you I bought an hp4 without the pillion package , looking back now I must of been stupid , yes you can buy all the bits second hand but second hand is never pristine and I won't settle for anything less , anyway now back to my point , check your logbook , your bike as mine is licenced / registered for one person , not 2 as it would of been if we bought the pillion pack . Could this affect insurance etc , have bmw screwed us for being tight buggers ??? Something to think about and look into for sure , plus will be a good excuse to tell the misses to sod off .
can anyone on here clarify this .
