Product Details

FMF Racing is well-known for making high-performance exhaust systems for off-road motorcycles. This RCT 4.1 slip-on muffler is built specifically for your 2009-2016 Kawasaki KX250F, aiming to give you a serious boost in power across the entire RPM range. It's designed to work with your bike's existing exhaust header, making it a straightforward upgrade.

This muffler uses FMF's Resonance Chamber Technology, both inside and out, to help improve the exhaust flow and sound. They've also made it shorter than previous designs, which not only helps centralize mass closer to the motor for better handling but also makes it less likely to get damaged in a crash. The construction uses aerospace-grade titanium for the main body, which is then blue anodized for a distinctive look, and it's finished off with a carbon fiber end cap. Everything is manufactured right there in FMF's Southern California factory, ensuring it meets their strict standards.

Because this is a slip-on muffler, installation is generally simpler than a full system. You'll want to ensure you have the correct tools to remove your stock muffler and install this one securely. The Rapid Tuning System (RTS) is also built-in, which can help with fine-tuning the performance for your specific riding conditions.
