FMF Factory 4.1 RCT Silencer (Manufacturer Ref: 044400)

The Factory 4.1 RCT Slip-On silencer is designed for quad riders looking to lighten their machine and centralise mass without compromising robustness. Designed and manufactured in California by FMF, it combines a titanium body with a stainless steel pipe and a carbon fibre end cap, featuring an anodised blue finish for a racing look that withstands the rigours of the terrain.

• Technology: Integrated Resonance Chamber Technology™ for controlled acoustics and harmonised engine response.
• Architecture: Factory Forward Engineering to bring the silencer closer to the engine and improve mass centralisation.
• RTS: Equipped with the Rapid Tuning System to facilitate engine optimisation according to settings and altitude.
• Premium materials: Titanium, stainless steel, and carbon fibre for a noticeable weight reduction and durability in off-road use.

Simple slip-on installation, designed to withstand shocks and the demands of off-road riding while offering a racing aesthetic. Ideal for Yamaha YFZ 450 R and RSE (2020–2022 models) and for any rider who values FMF's build quality and a pronounced sound without compromising on finish.
