FMF Racing KX125 03-07 Pipe Spring & O-Ring Kit P/N 011316

When you're working on the exhaust system for your Yamaha YZ125, especially between the years 1989 and 2019, having the right hardware is key to a secure and leak-free connection. This kit from FMF Racing includes replacement exhaust springs and O-rings, designed to work with either your original factory exhaust or an FMF system.

These are the small but important parts that hold your exhaust components together and seal the joint between the pipe and the muffler. Using fresh springs and a new O-ring ensures that your exhaust system stays properly aligned and that exhaust gases aren't escaping where they shouldn't be, which can affect performance and create unwanted noise. This kit is a straightforward way to replace worn-out or missing pieces during a pipe installation or maintenance.
