What has been the cost of the first service at 600 miles? Mine goes in this Saturday, just want to know what is fair. After that I'll do my own service.
Sounds like you are convinced! You don't have to use BMW's products but you do have to use products of equal specs or a warranty claim can be denied. So far I haven't been able to find a product (besides BMW's) that meets or exceeds their spec for the R18's final drive. It is your bike so have at it and good luck!!
