I do Vertex piston and had my crank rebuilt with oem parts by Millenium Technology. Very nice work!

You can use the PulpMX discount code at Vertex for piston, gaskets, wrist pin bearing. “pulpmxshow2018”

Prox and Athena are good. Avoid hotrods. I always upgrade my pistons to forged ones. Theyre stronger and you get more life out of them. CP, JE, and Wiseco are solid choices. OEM crank and nothing else. Bearings, get the best deal. A bearing is a bearing.

I used ProX rod kit and vertex piston in my 2011 250SX (same generation engine).
I bought a used cylinder from Ebay rather than replate my original cylinder. There are a lot of people that change from 250cc to the 300cc, so they sell good used cylinders. The used cylinder was cheaper than repair, and worked well for me.
I estimate my OEM conrod had 400hrs on it before failed. Unless your engine is damaged by dirt, or run without oil, the original cranks last an extremely long time. Check carefully before you waste your money.

Ok thank you
I used forged Wössner Pistons for the last 8 Years very good quality.
Not sure about the Crankshaft Rod , OEM KTM Part is 200€ here in Europe compared with a ProX Rod for just 95€ ?

Bearings are almost the same Price
