What header pipe for 2011 yz125


Recommended Posts

I have a fmf shorty silencer already so I would assume a fmf pipe unless the pro circuit bike works; the yz has athena 144 kit. I was thinking the fmf gold series pipe. Rocky mountain sells them for 215$ wondering if its a good deal or not. This is primary motocross bike just want to make sure this is a right buy over stock to give it a little extra power and I guess looks too.

I don't like the shorty with the stock header at all. Looses way too much over rev in my experience. My favorite combo was the fatty and the shorty silencer. Seems like that is what most people are running on their 144 kits.

does the fatty gold series come in the gold finish because its pictured as silver on rocky mountains website.

If you don't want to use stock definitely use a fmf fatty for a big bore.

Eric gorr recommends it and Harris performance dynoed it and it showed 1 to 2hp on a yz125.

If you search the post is on here somewhere.

Ya I tried searching all of about 5 minutes I just wanted a quick answer. Thanks for the help think im going to buy the fatty. My 250 has a fatty in a gold color is that the gold series?
