A good durable piston

It is a good durable piston and you get what you ask for. The only problem I have is that it doesn't come with the gaskets needed when you replace your old piston.

Great Product

I have used wiseco pistons in a number of bikes over the years everything from a RM65, YZ85, CRF250R and then this particular time in my sons 2012 YZ250F. His bike was way overdue for a new topend! Usually I have zero problems with the install, but this one was a little different. The circle clips were very difficult to install compared to previous installs, but with some patients and small set of needle nose pliers I got them in, what made it a bit frustrating was when I looked at the video on wiseco installing them the guy snapped them in with his thumbs like it was nothing. That was not the case with ours? Not sure if the guy had super thumbs or if ours were a stiffer clip? Either way, with some patients we got them installed. Second the center oil ring did not want to seat, it took several attempts to no avail to get it to stay in the groove as we put the cylinder back on, ended up having to use a different center oil ring. Not sure if we damaged it on our first install attempt or it was bad from the beginning? Again I have installed many of these and its the first time I have had problems with one. As for performance? Wow what a difference! The bike was way overdue for a freshen up and man did this new piston/rings make it come alive, my son felt like he had a new bike again!

Great product!

Great product!! Can never go wrong with Weisco! Package came in in great shape, and the sleeve they put the piston in was very nice to protect it as a extra measure. Would recommend anyone I know to buy this product!

Suttle Upgrade

Perfect kit, everything you need, all inclusive! A little power gain due to reduced weight of the piston compared to OEM

Love em!

I run the Wiseco pistons in all of my bikes and I've never had an issue. just stuck one in my newer crf450r and my old CRF450r has 65 hours on the Wiseco piston in it and still runs strong. These are a great aftermarket replacement option.

First time rebuild on yz450f high quality piston

I purchased this piston for my first rebuild on my 09 yz450f , the piston looks and feels great , it even shipped in its own cloth bag , like a bottle of crown royal, but install was a breeze and has been running very very strong since then . great product , the bottom end is also wiseco.

Great piston, would recommend to anybody looking to rebuild their bike. It went together perfect. And gave my bike a lot more power. (60hours on old oem piston.)

Piston

Went in easy into a cylinder that had 2 pistons before it and not even honed once. Raced hard and still running strong.

Quality Product from Wiseco as Always

You tell right away from looking at the piston that it is high-quality stuff. It comes with all necessary rings, pin and clips, but of course it's always a good idea to grab a gasket kit to go along with it. There was nothing difficult about install and it all fit and worked as hoped. My crf250r is 7 years old (basically a dinosaur in terms of motocross), and still had the stock top end in it. Needless to say the piston added a huge breath of life into the bike, and it is running like it was fresh off the factory.

I highly recommend Wiseco pistons for anyone in the market - they are about as high quality as you can find, and much cheaper than some competitors.
