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.

Yamaha OEM Top End Gasket Kit

OEM best
OEM Yamaha top end set cost alot more but quality is outstanding. Aftermarket base gasket (2 stroke) are basic paper type material. OEM has rubber type sealing beads around critical areas.

Wiseco Bottom End Rebuild Kit
Devin in SD
Right side crank seal
Only reason I did not give this kit a 5 star rating is it didn't include the right seal for one side of my crank. Had more down time waiting on more parts.. I have always trusted Weisco for quality parts and still wouldn't stray. But disappointed not everything was included for my yz250x. If you get this for the same bike get a right side crank seal with it!
