A few things, I acquired this data from an anonymous friend. I can't prove its validity or accuracy, nor can I guarantee or warrantee any validity for any other motorcycles than the BMW R18B that I purchased in USA. Countries/Regions/Models/Years will have differences so please, you use this guide at your own risk. I cannot stress this enough. Always consult a BMW Motorrad Dealer and if you can, buy parts & service from them so they can stay in business. I purchase all of my BMW parts from my dealer and have my bikes looked over once a year despite doing my own maintenance.
