Product Details

FMF Racing is well-known for making high-performance exhaust systems for off-road motorcycles. This Factory 4.1 RCT muffler is built specifically for your 2009-2016 Kawasaki KX250F, designed to give you a noticeable boost in power across the entire RPM range. It's a solid option if you're looking to get more out of your bike's engine.

This muffler incorporates FMF's latest Resonance Chamber Technology, both inside and out, which helps improve exhaust flow and engine performance. They've also made the muffler shorter, which not only helps reduce the risk of damage from impacts but also moves the muffler closer to the engine. This centralization of mass can improve the bike's handling by keeping weight distribution more balanced. The construction uses aerospace-grade materials, and the muffler itself is finished with a blue anodized titanium body and a carbon fiber end cap, giving it a strong look to match its performance.

The Factory 4.1 RCT also features their Rapid Tuning System (RTS), allowing for adjustments to optimize performance. Everything is manufactured at their Southern California factory, ensuring it meets their strict standards. This muffler is a direct fit for your KX250F, meaning it's designed to bolt on without needing modifications.
