## BMW R850: A Versatile and Long-Lived Motorcycle Family The BMW R850 series, produced from 1994 to 2005, represents a significant chapter in the history of the German motorcycle manufacturer. This line of air-cooled, boxer-twin engines offered a diverse range of models, each catering to different riding styles and needs. From the sporty R850 R and R850 RS to the adventure-focused R850 GS, and the luxurious R850 RT and R850 LT, the R850 family provided options for everything from commuting and touring to off-road exploration. The R850 series was characterized by its innovative features, including the introduction of a new air-cooled, 850 cc boxer-twin engine with a 90-degree cylinder angle. This engine, while sharing some components with the R1100, offered improvements like a lighter crankcase and a new, more efficient combustion chamber design. This resulted in increased power and torque compared to its predecessor, while retaining the renowned reliability and smooth running characteristic of BMW boxers. The R850 also featured a new single-sided swingarm, offering increased tire clearance and ease of access to the rear wheel. The addition of a catalytic converter on most models further enhanced the R850's environmental performance and improved its appeal for riders concerned with emissions regulations.
