Complete kit
Installed on my 09 xcw300 all gaskets included including those needed for power valve. Assortment of base gaskets made setting Z measurement easy and accurate. Piston is top notch. All I would recommend is purchasing EZ clips as the wrist pin clips provided are difficult to install.

Good but not perfect
Vertex top end kit for KTM SX85 2012. Everything fits fine except the exhaust gaskets. They are slightly too big and will not seat in the pipe grooves. Photos sent. No, its not an aftermarket pipe.

Great Price, fast shipping
I just installed this top end in my sons kx 65, easy install, came with everything needed to do the complete job. Still cold here so haven't rode it yet but I did fire it and do a heat cycle, everything sounded great.

Missing parts
The kit had most but not all the required parts. The o rings for the power valve are missing

Not as advertised
The kit did not include all the parts as indicated. I did add my bike and it did indeed say it was a guaranteed fit. Which is true, the piston fit. Bun it did not include all the o rings needed for the power valve

Great top end kit.
Nice kit, came with any gasket or seal you could possibly need for the job. Everything fits perfect.
