Have been looking at the R/R on my Kawasaki zzr600, also the one on a Kawasaki zxr250A model and a brand new one that I have that was purchased to fit another ZXR250A model. Here's my dilemma...can't figure out what some numerals are printed on the casing???? This is the one on the zzr600 This is the new one for the zxr250 The part numbers I'm OK with.....what I wanted to know is the numbers below the part no. ???? Probably of no value, just curious if anyone knows.
