Topic: CB550 K1 genuine master cylinder rebuild kit

[Erny]

preparing rebuild of MC - is it possible to get genuine Honda rebuild kit?
Looking in spare part catalogue (partzilla, cmsnl..) it is shown in the picture but not listed as spare part.. strange

it is for CB550 K1 1975 (built in 1974)
complete  MC shall be 45500-341-771
item 25 here : https://www.partzilla.com/catalog/honda/motorcycle/models-with-no-year/cb550k1-a/front-brake-master-cylinder

Looking for part number or top quality alternative

 For about $3 more than a rebuild kit. I and many others have used this one several times. Best bang for the buck out there.

I agree that buying new one is more econimical, but I want to keep bike 100% stock.
