Piston cracked after installing supplied piston rings
I installed the piston rings on the piston and after doing so I was rotating the piston to check the rings and noticed a crack had formed along the wall of the piston. Since this is going into something that will be held at high rpm for long periods the crack renders the piston useless.

Not for PW50!
This is the wrong piston for a PW50, as others have stated.I was fighting with another Chinese garbage set, purchased via the other popular selling site, and those had mis-machined ring grooves. I found this in my stash of parts, and could not figure what it was for... right diameter, but way too short to be a PW50 piston. My purchase history showed I bought it here.Wrong for a PW50... you've been warned!

Does not fit what is advertised
As you can see piston is not even same size as original the rings won’t even work on the old piston

Does not fit a 02 pw50
The piston I received was way to short. Not the right piston for a pw50. Glad I ordered two from different companies the other one was perfect.

Piston Pin bearing was not included.
The Piston Pin bearing is shown as a piece in the photo of the kit but it was not included. Disappointed when I opened the package.

Not the right product
This is not the correct piston for pw50 do not buy this product!I have an 06 and a 10 pw50 its nothing like its way too small correct diameter 40mmRubbish brittle rings one snapped so probably can't send it back.Waste of time and money.

DID NOT FIT.... WASTE OF MONEY
Completely useless.... Should have guessed really for the price.... But at least it should have been the same dimensions as original piston... Not 15mm short.... on the crown side.... so there would have been no compression.... WASTE OF MONEY

Que no valía para la moto en cuestión
Lo tuve que devolver porque no tenía las medidas del anuncio y no se adaptaba a la Yamaha pw50
