If you are installing a new piston, I suggest a Pro X piston kit. It’s a cast piston, so it’s a little heavier than forged, but it costs much less. Pro X is distributed and supported by Wiseco, so if you have any questions you can just call.
I already put together an article covering piston selection so I’m not going to go into that here, but a cast piston works for me, because I will be installing it in a bike I use for enduro.
But just in case you’re curious, here are your options. (Links to Amazon)
