Unfortunately not.
I pointed this out to BMW UK, as part of a short set of exchanges on this, that included the reasons why I felt this was a corporate mistake and why I thought it unfair to expect dealers to pick up the tab for their cost savings. The final email from Customer Service included this:
"We can confirm that this situation remains as described in our previous communications and that BMW have made the decision to supply only one key as standard with our motorcycles and this decision has not been taken in error.
We would again suggest that you may wish to discuss your unhappiness with the BMW dealership handling your order and should the dealership feel that any additional action is appropriate once they have discussed this with you,
then they have the means to contact BMW UK on your behalf to query this or to give consideration to whether they can find a solution for you themselves. Alternatively you may wish to consider purchasing a replacement key for your BMW should you feel it is likely that this would be required at some stage in the future.
Once again, we appreciate that this is not the response you would have hoped for and would like to apologise for the disappointment you evidently feel, however whilst any further correspondence on this matter shall be read with interest, no response would be forthcoming."
So that is that.
Unless you know otherwise ....
