The 850cc and 100cc engines have been used in numerous BMW bikes ever since they were launched back in 1993. They all use fuel injection and four-valve heads. There isn’t much that you can call a frame on most of them, the massive engine and gearbox castings are used as load-bearing members and have the front and rear suspension bolted to them. Both engines have proved to powerful, smooth and most importantly, reliable over the years. At Haynes, we have an extensive range of BMW repair manuals and online maintenance procedures available for professional mechanics and DIY car enthusiasts. Our repair manual for the BMW R850 and R1100 is here to help you through every stage of servicing or fixing your motorcycle.
