Expert Pro-Tip

Expert Pro-Tip: When upgrading to a high-flow exhaust on a CRF125F, don't forget to check your air intake. These small bikes are often choked down by the stock airbox. Installing an aftermarket high-flow air filter alongside this muffler will help the engine breathe even better, allowing you to fully realize the power gains the FMF 4.1 system provides.
