OEM Honda Grom 125 Piston Rings-STD (2014-2020)

Rebuilding your Grom's top end? Don't cheap out on the rings. This is the genuine Honda OEM standard-bore piston ring set (P/N 13012-KYZ-900) for the 2014-2020 Grom 125 — the exact rings that came in your motor from the factory, engineered to match Honda's bore tolerances and cylinder finish right out of the box.

If you're running a stock 52.4mm bore and freshening up a tired engine, these are what you want. Correct ring geometry means proper seal, proper compression, and no guesswork on end gap the way you get with some aftermarket sets. Slap 'em on a fresh piston, hone your cylinder, and you're back to factory-spec sealing.

What you get:

• Complete OEM ring set for one (1) piston set includes top ring, second ring, and oil ring assembly
• STD (standard) size — for stock, un-bored cylinders only

Fitment:

• Honda Grom 125 (GROM / MSX125) — 2014-2020 
• Standard bore: 52.4mm
