Drive shafts have been used on [[motorcycle]]s almost as long as there have been motorcycles. As an alternative to [[Chain drive|chain]] and [[Belt (mechanical)|belt]] drives, drive shafts offer relatively maintenance-free operation and long life. A disadvantage of shaft drive on a motorcycle is that [[gear]]ing or a [[Hobson's joint]] or similar is needed to turn the power 90° from the shaft to the rear wheel, losing some power in the process. On the other hand, it is easier to protect the shaft linkages and drive gears from dust, sand and mud. | Drive shafts have been used on [[motorcycle]]s almost as long as there have been motorcycles.
