I would have taken this to the press some time ago as it's the most proven way of getting a response out of any publicity-sensitive company.
Don't be shy, write up the incident in the most sensationalist way you can imagine (read a copy of the daily mail for preparation) and badger every motoring journo in the UK to publish. Point the journos in the direction of this board for corroborating stories and they'll have a field day.
In the meantime forward your article to both DUK and Freddy Minolo as food for thought. If you're vigilant I'm sure they will come round to your way of thinking.
Do not lay down and take this, you deserve a full rebuild or a new bike, not some new brake bits and a fob-off.
