Features

FMF Factory 4.1 RCT - Exhaust System (Manufacturer's Ref: 044483)

Designed for off-road and motocross competition, the Factory 4.1 RCT combines material choices and modern architecture from FMF. This compact canister silencer brings the mass forward for better centralisation, while reducing bulk and exposure to impacts in case of a fall. Machining and assembly are carried out in the Southern California factory using aerospace-grade materials.

Technology: FMF Resonance Chamber Technology™ integrated both internally and externally.
Collector: stainless steel for heat resistance and durability.
Silencer: aluminium body, grey anodised finish.
Tip: carbon fibre tip, black end for a sleek aesthetic.
Configuration: single canister, reduced overall length to limit damage risks.
Manufacturing: 100% Southern California production, FMF specifications.

Important Note: This system does not comply with FIM 2025 sound regulations. Check sound compliance according to your use and territory before installation.

Compatibility (examples): YAMAHA YZ 450 F 70th Anniversary Edition (2026), YAMAHA YZ 450 F (2026).
