I can’t believe I didn’t notice this until today ( \uff9f\u0414\uff9f)
My apologies.<\/p>\n\n\n\n

Does this look familiar? It’s an outer dust piston…

Wait! Could this be… a GS\/GSX series rear?<\/h2>\n\n\n\n\n\n\n\n

*Dust seal groove diameter

Since it’s used, being in the 100 range is good enough. They’re completely identical and fully compatible \u25ce (*^-^*)<\/p>\n\n\n\n

69100-08821 can be used as a substitute. Comes with piston, dust cover, and oil seal.
The piston and oil seal (which also have the same part number 59107-18410) can be used as-is, but the dust cover has a different outer diameter so the one in the set cannot be used.
59108-16700 GSXR dust cover will need to be sourced separately.<\/p>\n\n\n\n

I hope this helps someone out there… (\/\u03c9\uff3c)<\/p>\n","protected":false},"excerpt":{"rendered":"
