I telephoned BMW customer service and queried if I did it myself would it invalidate the warranty. "No" was his reply as long as you use genuine BMW parts and the correct lubricants, .
That is correct.
I've never had a problem with any warranty claims on bikes i've serviced, and i'm one of the longest independant BMW garages, 24 years and still counting
. Forget the scare stories you may have been told about having to be VAT registered etc etc, it's just not true.



I shall do the same with my GS too. (only had it a week, and now away on business for a couple of weeks...weathers lovely in San Francisco BTW :cool )
