Production numbers were: 1973 RD60 - 2,440; 1974 RD60A - 3,170; 1975 RD60B - 6,170. The RD60 was the junior member of the Yamaha RD Series. It has an Autolube oiling system, which is an oil pump that is actuated by the throttle cable. Users have reported these failing and recommend to run premix.

Repair and Maintenance

See exteral links at bottom for parts and parts diagrams.


-The RD50 and 60 have nearly interchangeable parts, and Blake of Doscycles confirms that the DT50 MX has a similar bottom end here. There are also many parts that overlap with the GT50 and GT80, as well as the YZ series. YMMV.


  • At some point, Homoet made a clear-coat pipe that looks pretty nice.
  • Stock carburetor is a bolt-on Mikuni VM15.


I plan to keep updating this thread as I compile and collate. Please feel free to add anything I've missed, or correct me if need be.
