Whats a BMW Racing Technician? A Factory BMW Technician still wont be a trained suspension technician.
Other than hoping that you have a unit that does not have this issue, or if you do getting BMW to take ownership, not alot..!
Stock suspension is and always will be built to a budget - you should see some of the Tricks that Ohlins pull on their OEM Clad suspension because it certainly is not R&T Grade! I have a seperate post on the vendors page about OEM Suspension.
As for a Racing bike, nobody sticks to stock DDC Suspension unless they do not have the budget or the regs of their club do not allow them to run aftermarket suspension. In our BMW's we run Ohlins but it costs a pretty penny for the contract, the brand is the team owners choice and personally i'd be aligned with K-Tech but that's by the by. Very few riders even in BSB have a say about the brand of suspension in the bike because they don't build it, you will normally find teams will change if they get a better offer or they find a problem which could be attributed in part to the suspension.
That very thing happened this year in BSB, switched from years of running their bikes on Ohlins to K-Tech, and the Thru rod systems (TRDS) which is not available to joe public as of yet.
Anyhow I diversed, as for Oldwobbler's comment, I could not agree more.
