Production data Yamaha RD125 1973 - 1986
It can be very hard or sometimes even impossible to find production data for Yamaha's from the seventies. Apparently Yamaha didn't keep record of their production data back in the days... or maybe those books are laying, covered in dust, somewhere at an attic.. who knows. Thanks to Yamaha Australia I got production numbers of most of the Yamaha RD125's. I've put them together in an Excel file to give you an idea of the numbers of Yamaha RD125's ever made.

Basically the Yamaha RD125A is the same as the 1973 RD125. The 1973 RD125 was sold in Europe as the Yamaha AS3. If you're looking for parts for your 1974 RD125 A, you can use the 1973 RD125 parts manual (download http://www.yamaparts.com/manuals/ ) , however there are some minor differences which you can find in the RD125A supplement (4 pages, see below).
