I confess I don't know how it works outside of the United States, but BMW cannot void your warranty here if you do your own service on the bike, unless they can prove you made an unauthorized modification or was negligent in the performance of the service, such as leaving a drain plug loose.And BMW voids your warranty
We have specific consumer protection laws that don't allow them to do that. For instance, if I bought a new bike and changed out the air intake and air cleaner to an aftermarket brand, they can't void my warranty for that.
