Its winter and time for me to get mine ready for the spring.
Can I order a FMF Pbomb/Mbomb with PC4 made for
YZ250F fmf exhaust for WR250R
WR250F fmf exhaust for " R "


I am really not trying to order something that wont fit...
the websites keep saying wr250f or yz250f but dont mention the wr250r
thanks

They would not fit at all if you're expecting to just bolt it up and go - nothing will line-up correctly because the bikes are different.

I saw a YouTube video of a foreign guy who put a YZ-250F muffler (unknown model year) on his WR-250R.
He had to do some custom bending and bracket fabrication.
I thought it looked too backyard, but he seemed to like it.
