Got to confess i'm not entirely sure what 'winter service' entails. I suspect (though i don't factually know) that it's checking brakes, fluid levels etc etc.
I got rear ended a few days before i got on the bike so it's possible it's partly in my head, will get a brakedown of what they did to the bike next week though as apparently the cush (?) drive needs replacing by the Dealer too.
i'll check the bits you guys pointed out though, see if there's anything that looks odd there.
cheers for the help guys
