      Hi!
      I'm about to replace the chain kit on my 1995 DT 125R, and want to do the 520 pitch upgrade - I know people are fitting sprockets from an earlier YZ 125, but from which years can I fit?

        I knew it was 2004 front sprockets 520 fit. But that era of YZ runs 428.

        If you go to B&CExpress they sell the 520 conversion kit. That's what I bought

          @Calum I wanted some options in ratios, so that's why I didn't just order a complete kit - did some research and learned that following JT sprockets fit:

          Front - JTF 564 (for an example, JTF 564.13 is a 13 tooth 520 sprocket)
          Rear - JTR 853 (for an example, JTR 853.50 is a 50 tooth 520 sprocket)

          Thought this might be helpful.
