Suzuki GS 650 GT (1981-1983).
Suzuki GS 650 G Katana (1981-1982).
This ignition coil set has been manufactured to replace the original coils on a GS650 for the years and models shown above.

90mm from centre to centre mounting with 2 connectors and 2 HT leads.
If you have a weak spark on your Suzuki GS650 then the ignition coils (or plugs / plug caps) are the likely culprit and it's a good idea to get these replaced especially as the original coils are all now over 40 years old.
