Pro X Piston Kit
Geoffrey in OK
Works like a charm
Piston works as intended! Just make sure to look for the STAMPED arrow to point toward the exhaust port not the ink stamped marking!

Vertex Piston Kit Standard
Jay in VA
Vertex Top-End Piston Kit - 2022 CRF250RX
Installed the Vertex piston along with a Tuck gasket kit on my 2022 CRF250RX with 75 hours on it and everything went as expected. Raced on it after break-in and experienced no issues whatsoever. Vertex is still quality and I've never had any issue with their piston kits. I'd recommend them.
