About this part

Product Details

If you're looking to get more out of your 2004 Honda CR125, this FMF Racing Fatty Pipe is a popular choice for riders who want to improve their bike's performance. It's designed to broaden the powerband, meaning you'll feel a noticeable increase in power across a wider range of RPMs, not just at the very top or bottom. This translates to better throttle response and a more engaging ride, especially when you need to accelerate quickly.

FMF is well-known for their exhaust systems, and the Fatty pipe is their best-selling model for a reason. It's built using their Tru-Flo stamping process, which helps ensure a precise fit on your CR125. This means installation should be straightforward, and you won't have to fight with the pipe to get it lined up correctly. The pipe also comes with the necessary O-rings to complete the installation.
