520 pitch sprockets from YZ 125 - which fit?
@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.
