Yamaha ID serial numbers

[albrid-3]

The engine number on that 400 mx is 574, is a Dt engine, as the clutch cover is not YZ or MX. Does anyone know what model it is.

[IT400C]

574 = 1976 DT400C

You just have to remember that they are model codes and not engine frame numbers.

With the earlier bikes the engine/frame numbers may be different to the model codes.

i.e.:
The IT400C model code is 1K7

The IT400C engine/frame numbers are 510-2*****

The only place you see the 1K7 is in the part numbers for bits specifically designed for the IT400C.
