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.
P**.
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
