No, not all BMW motorcycles use shaft drive. While BMW is known for offering a number of motorcycles with shaft drive, they also have models that utilize chain drive and belt drive systems.
Shaft drive is a type of final drive system that transfers power from the engine to the rear wheel through a solid shaft. It offers benefits such as reduced maintenance and longer service life compared to chain drive, as it does not require regular lubrication or adjustment. Many BMW touring and adventure models, such as the BMW R 1250 GS, R 1200 RT, and K 1600 GT, feature shaft drive.
Chain drive systems are lightweight and allow for precise power transfer, making them popular among sportbike enthusiasts. Some examples of BMW motorcycles that use chain drive include the BMW S 1000 RR and the BMW F 900 R.
In summary, while BMW is known for its shaft-driven motorcycles, they offer a variety of models with different drive systems to cater to different riding preferences and purposes.
