This high-performance FMF Factory 4.1 RCT Titanium Anodized Slip-On Silencer is designed for the Yamaha YZ450F models from 2018 to 2023. Crafted with FMF Resonance Chamber Technology™ and aerospace-grade materials, this silencer offers improved power delivery and durability.
Its shorter length minimizes crash damage, while the carbon cap enhances the overall aesthetic and performance. The design focuses on centralizing mass, bringing the muffler closer to the engine for better handling.
