There must be a very slight difference as Wiseco lists a different part number for all the piston sizes after 1982 for the 125.  But the same part numbers are used for the rings, clips and pins for all years. They are even the same external dimensions.  You can just go Wiseco for the H as they have a tonne of pistons for it anyway.

There was someone who had a piston kit to fit yz125 from 1976 to 1981 on ebay. I was just wondering if anyone new if these pistons are the same. As for Ricky Stewarts problem my clutch bush was floged out as well but I had an early DT 175 engine and found the clutch bush was the same but just a bit longer and just needed linishing down to the same length. You will probably find all DT yamaha's use the same diameter bush.
