FMF Racing Yamaha YZ125 2005-21/YZ125X 2020-22 Factory Fatty Pipe

If you're looking to get the most out of your Yamaha YZ125, especially for trail riding or open-class motocross, a new exhaust pipe can make a big difference. This FMF Factory Fatty pipe is designed specifically for your YZ125, aiming to improve its performance and give it that classic FMF sound.

The engineers at FMF have used a lighter gauge metal for the body of this pipe, which helps achieve that signature FMF sound. The header section is constructed from 19-gauge steel for durability where it counts, while the body uses a lighter 20-gauge steel. What really sets this pipe apart is the hand-pounded seams. This technique creates smoother transitions inside the pipe, which helps the exhaust gases flow more freely. Better flow means your engine can breathe easier, potentially leading to improved throttle response and overall power delivery.

This pipe is a direct replacement for your stock exhaust, and it comes with the necessary O-rings to get it installed. It's a well-built component that's popular among riders looking for that extra edge.
