Give your classic GSX400F a fresh lease on life with this genuine Suzuki piston ring set.
Part number 12140-33215 is the original factory ring set used on early-1980s Suzuki GSX400F models. Suzuki later superseded this number to 12140-33310 for the standard size, but the application remains the same.
This kit includes the full set of rings to service one piston – ideal when you’re re-ringing a good piston or doing a correct OEM-spec rebuild on a period bike.
