Brand new ignition coil to fit:
Honda CB 250 RS (1980).
Honda CB 250 RS (1982-1983).
This ignition coil has been manufactured to replace the original coil pack on a Honda CB250 for the years and models shown above.
100mm centre to centre mounting with 1 connector and 1 earth wire. Your original may not have a separate earth wire, this coil is still correct to replace that coil. Just attach the earth wire to the mounting bar when you bolt it down to the bracket / holder.
To replace OEM: 30500-437-000 / 30500-437-010.
If you're having spark issues (weak spark or no spark) with your Honda CB250, then the ignition coil could be the culprit and it's a good idea to get a new coil on the bike.
