Wiseco quality
I replace this bearing Everytime I change the top end or Piston ring of my yz 125. Wiseco should include this bearing in the Piston kit. Never had any problems.

Nice smooth looking wrist pin
Hard to say much about the brand anybody that’s heard of wiseco they know it’s good stuff just may be a little more price just because of its name

Couldn’t find a top end kit for my sons bike that I could get quickly. So ordered piston and ring and the wrist pin bearing separate and got next day delivery. Well worth the extra $20 to have it the next day!

Get the OEM bearing from RM it's a lot better.
The Wisco bearing has 15 needles that measure 0.525" the OEM bearing has 17 needles that measure 0.625" the OEM bearing is superior to the Wisco. RM carries both for a comprable price.

Qulity products!
Been using Wiseco pistons/top end parts for years with great performance and durability. Wrist pin bearing fit and performs like the stock bearing. Will be using them in the future.

Perfect Fit, Nice Quality
Always have trusted the Wiseco name when it comes to top ends, especially replacing the wristpin bearing. Fit was great and feels like an quality component.

Will this work with an oem piston or does the piston have to be wiseco?
michael a on Jan 7, 2017
BEST ANSWER: Yes wiseco wristpin bearing will work on oem piston. It's also good to make sure crank bearings are in good shape with no play in bearings. Not sure if your replacing ring to but this would be good to do as long as cylinder and post are in good shape.
Will this work with the vertex piston?
A shopper on Jul 22, 2019
BEST ANSWER: This a replacement for Wiseco Pistons only.
