1975 Yamaha RD125 Service and Repair Manual

Yamaha issued this book under part number LIT-11616-10-12, and it is the reference the factory expected a dealer technician to keep on the bench while working on the RD125B.

Because the same volume was written to serve the 1975 and 1976 machines, and the RD200 alongside them, the specification tables are laid out side by side. That matters when you are chasing a clearance figure: read down to the column that carries the RD125B code rather than taking the first number on the page.

What the book carries

• Engine and transmission teardown with assembly sequence and torque values
• Carburettor settings, ignition timing and point gap adjustment
• Frame, suspension, wheel and brake service limits
• A wiring diagram and a fault-tracing section for the charging and lighting circuits

Check the code stamped on your frame against RD125B before ordering, and confirm the part number matches LIT-11616-10-12 if you are comparing this against another listing.
