To decode the VIN of a 1975 Yamaha RD200, start by locating the 17-character VIN, typically found on the frame or the engine. The first three characters represent the manufacturer (Yamaha), the next five denote the model and engine type, while the following characters indicate the production year, assembly plant, and the sequential production number. For a 1975 model, look for the year code, which should reflect that specific production year. You can also refer to Yamaha's VIN decoding resources or forums for detailed information specific to your model.

I think it will. If you look at biebandit.com and find the oem Yamaha parts for the motorcycles in question and check to see if they are the same part number, if they are then they will interchange. you can crosscheck different years too if you found a 1975 ty 175 cylinder for your 1975 dt 175. So check out bikebandit and see for yourself, they are the next best thing to a Yamaha dealer.
