Worked great until catastrophic FAILURE

Comments On Mar 12, 2014:Installed in my 1999 CR250 along with newly re-plated cylinder to factory specs, worked well until skirt on intake side shattered and destroyed engine cases, cylinder, and head. Engine was fully warmed up and jetted correctly when the failure occurred. I have used vertex pistons in my ktms without problems for years, but can not recommend in Honda bikes.

Very Good Piston

Comments On Mar 11, 2014:In my opinion, the best aftermarket pistons for KTM 2-strokes. Have always used Vertex pistons and always will. Long Life and never an Issue

Only piston I'll use!

Comments On Dec 28, 2013:This is a very high quality piston, it looks identical to stock. After seeing the prices of a OEM piston kit, I decided to go with this and I couldn't be happier. So far I have put 60 hours on the piston and it still has strong compression. I recommend this piston to everyone!

Quality replacement

Comments On Nov 17, 2013:Good looking product and fit just fine. The only reason for the downgrade is due to my hatred for the wrist pin retainer clips that come with these kits. They could do better. I know they're the same as stock - but these are extremely difficult to install and often results in marring the piston up by the time you're done. They could use a different type of retainer clip that would cause buyers much less difficulty.
