Doing a top end refresh, valve job, or big bore build on your Grom? Don't cheap out on the little stuff. This is the genuine Honda OEM valve stem seal (part #12209-GB4-681) — the exact same NOK seal that came on your bike from the factory.
Valve stem seals have one job: metering the right amount of oil to the valve stem and guide. When they get old, hard, and brittle, you get that classic puff of blue smoke on startup, oil consumption creeping up, and carbon building up on your valves. If you've got the head apart for any reason, replacing these is a no-brainer — they're cheap insurance against burning oil.
Aftermarket seals can be hit or miss on material quality and fitment. Genuine Honda means exact OEM specs, proper oil metering, and no guesswork.
