I thought about making a couple posts with some "exotic" PGM units.
This one is a PgmII unit for Nsr250 F3 MC21 bikes. Even though it was available in the past, F3 parts are now obsolete.
The Nsr250 mc21 originally used a PgmIII unit and there were a few HRC Pgm3 units for the SP Production racing as well but HRC choose a simpler yet effective Pgm2 for the F3 category.
All SP racing parts have the code NKD while FIII racing parts have the code NH3.
I've used this PGMII unit on my Nsr250 racing bike with a modified MC18 wiring loom.
