cat in exhaust?

Recommended Posts

Hello, in my searching for info on exhaust options for my 2019 wr250f, I ran across a few threads that mentioned a catalytic converter in the head pipe on these bikes. I had my silencer off so I tried running a flexible aluminum welding rod up the head pipe and couldn't feel a restriction. I'm guessing that the cat is a European spec requirement, and hopefully not applicable to the US bikes? Thanks for any response or info.

EU bikes have one fitted by the EU importer's agent to make them road legal. They are not fitted by Yamaha Japan.

It is located at the first joint on left hand side of bike above the stator

Very easy to remove if fitted

Thank you for the info. I would assume that since the WRF is not intended to be road legal here in the states, that a cat would not be installed?

I doubt any WR250F sold in the USA came with the cat. in the header pipe or muffler because it's simply not a requirement for off-road use.

Yet.
