250-500cc New Top End recomendations

I have a 2008 WR-250 that's due for a top end. Do you have any Pro/Cons to the aftermarket pistons or should I stick with OE? I haven't even looked at the cost yet. Thanks!

I would recommend the OEM/vertex piston. "If you want to rock, keep it stock"..

+1 for Vertex. I ran a bunch of them in my KX's also. The engines always ran the best with Vertex pistons.

Wossner has worked fine for me.

Really liking the Wossners also.

Guys, what kind of hours are you putting on a Husky top end. My '08 WR250 has about 80 hours on the original OE piston. It looks smooth and clean. My performance is still tight, crisp and the bike rips. In the past, I would run my KTM200's for 100 hours or more and they would still look like brand new when they came apart...

I have an 08 as well.I did the top end @ 70 hrs right before racing season began.Everything was well within specs but I still replaced with a namura top end kit.This was in bike until I did something stupid @ 180 hrs.I got lazy and didn't check my air filter placement after install.The bottom of it was hung up on lip,this was the first and only time I didn't feel around the filter with my hand.I ran in a very dusty scramble and the bike quit @the beginning of the fifth lap.The entire top end looked like it had been sanded down to bare metal(because it had).I replaced cylinder and installed another namura top end.This has about 57 hrs on it.The first namura had 110 hrs on it and was still making great power.

I normally run a top end about a year, but I can't honestly tell you how many hours that is. I know that even after a year of having it's guts wrung out the pistons still look good. Like they could do another year without a problem. I really think that if you have them jetted right and keep the filter clean, they are pretty bullet proof.

Between 250-300hrs on my original topend. Piston and rings worn, cylinder looked new.

Crazy!- Love it.

Well, I think I'll hold off a little longer. I have a 7 mile single track loop behind the house and I only ride about 2-3 hours per month when the conditions are perfect. Thanks for the help.
