As an OEM supplier vertex is quality. they supply ktm husky and husaberg. i have not had a failure in 2 years of running this brand with over 300 hours of use. that is 9 top ends!! and i have over heated the engine so bad that the piston pin changed color. still no failure. the rings are always in spec and i have not had to file a set yet. the pistons has also been in spec and true every time. call them they have a great tech support.
Quality rebuilds that work everytime! I live in Iowa and motosport puts this stuff in my doorstep in 2 days for free!! Can’t beat them! Vertex also coats piston to help with break in. I’ll be a customer as long as my son is running minis!
Funny how a manufacturer printed box is more expensive than the vertex box.
Flip a “ktm” piston over and it’s stamped vertex inside.
Still going strong almost 3 weeks later
Like that Vertex offers the "B" Piston for the YZ 250. Nice piece, well made, & I replace every 30 hours.
This is my second time using this kit for my 2012 KTM 150 XC. Beware that the wrist pin for the KTM 150 XC kit are real tight. You will need to use a light coating of grease to get the pin in the piston. Other than that, it's a nice kit. I got 60 hours on my first kit.
Able to get a solid 25 hours of race plus trail riding out of this Piston. found no wear after 25 hours.
bought it for 98 yz250 got my heat cycles in then rode down at the dunes blew up right when I got on the pipe I assume power valve hit and now cylinder is screwed but piston installed good had a nice coating and ring gap was spot on
