Email's from BMW
"I trust you will understand that we rely on our network of BMW Motorrad Approved Dealerships to act in the capacity of our technical advisors. Their field reports is then utilised to help us identify trends in component failure. As previously advised, the S 1000 RR Sport has not been highlighted as having an inherent issue with the sump. Should this situation change as we receive further details, we would then look to address it through a quality enhancement. If you have any specific questions in the meantime, I will endeavour to answer them."
"[FONT="]I can advise that I have contacted our Technical Department for further advice regarding the questions that you have. I can confirm that we collate all failure reports to establish if there is a failure trend with any parts. Any information in the report is for internal use only. However, I can advise that there has not been any metallurgic problem with the sump, therefore, there has been no changes to the part."
"[FONT="]I appreciate that you have concerns regarding the reliability of the part and you would like to know what would happens if it fails once the warranty has expired. Once the two year warranty has expired we do encourage our customers to purchase an Insured Warranty, to offer additional peace of mind. In the absence of a valid warranty policy we do operate a goodwill policy. If the sump was to fail on your motorcycle and you did not have any warranty policy in place, we would review your case favourably."[/FONT][/FONT]
