Bad wrist pin circlip
Jared in TN – Machine this part was bought for: 2005 SUZUKI JR50/R
Comments On May 03, 2013:This OEM equivalent cast piston appears to be of good quality along with the wrist pin and piston rings. However, the wrist pin retainer circlip is poor quality. The circlip is oversized, overly stiff, and could not be installed without permanently bending it. Why bother making these parts if you mess up the easiest and cheapest component.

Good for the current application
Jeramy in VA
Comments On Nov 21, 2012:This isn't going to help much as I used this for my son's little JR50 dirt bike. All i can say is it works as it should and after about 15 to 20 hours all is well.

Identical to stock, except one problem....
KENT in ID
Comments On Sep 18, 2012:I held this piston up next to my stock piston and could not see any difference at all. (A Wiseco, by contrast, looks quite different than the stock piston on my KTM 300 XC- W 2009.) There is one problem though, the wrist pin circlip is way way harder to install than on the stock piston or on a Wiseco. I looked carefully to see why and noticed the Pro-X circlip holder was not tapered, but was squared off. This is a minute difference you would never see, untril you try to "tap the circlip" into place and it won't go. If you are really dexterious this won't be a problem but I got very aggravated and decided not to buy one again. Once in, the piston has worked fine and been very durable, now having about 2,000 miles and only slight loss of compression.

Poor quality
DAVID in CA
Comments On Aug 30, 2012:Bought Pro-x instead of Vertex for the first time for my KTM 144sx. Piston was installed correctly into a good cylinder, synthetic premix, good jetting, heat cycles, etc. Piston scuffed and lost all compression after 15 min of riding. Installed the old Vertex (which was in great shape after 30hours ) and have been through 2 tanks of gas with the same premix and jetting, no problems. Pro-x said lack of lubrication and will not warranty. I will never buy their products again.

good
Robert in NY
Comments On Jul 18, 2012:installed. no flaws with the design or product. It is a great product, but doesn't compare to the forged wiseco's. This pro x piston replaced a high end cast piston... i might buy again depending on how many hours i get out of this piston.
