If you ride any R-Series bike, even one of the latest models equipped with every advanced technical innovation, you’re riding a direct descendant of the first motorcycle BMW ever made. Yes, the two-cylinder, horizontally opposed motor that Max Friz designed for the R32 in 1923 lives on in the DNA of your machine. At the heart of all BMW R-Series motorcycles is the “boxer twin” motor which earned iconic status from the moment it was born, then evolved in very exciting ways into the 21st century, and continues to inspire dedicated fans the world over.
