Fitment first
Model code RD200B, Yamaha part number LIT-11616-10-12. Both need to match before this book is any use to you.
Yamaha chose to cover four machines in one volume here — the 1975 and 1976 RD200 together with the RD125 of the same two years. The shared procedures are written once; the numbers that differ are broken out by model code in the specification tables, so you read across to the RD200B entry.
What you get is the dealer-level reference: adjustment and maintenance schedules, engine removal and complete teardown with torque figures, carburettor and ignition settings, clutch and transmission work, chassis and brake service limits, plus wiring diagrams and a troubleshooting section for the electrical side.
It is written for someone with tools in hand rather than for reading on the sofa, which is the point. Steps assume you can identify components and follow a sequence.
