Product Details

The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology (RCT) — both internally and externally. A patent-pending shape enhances and refines the exhaust pressure wave for optimal power output while lowering the sound level. Constructed from aerospace-grade titanium with a carbon end cap, the system is shorter, lighter, and quieter than stock.

  • FMF Resonance Chamber Technology (RCT) for power + quieter operation
  • Aerospace-grade titanium construction with carbon end cap
  • Shorter overall length — less crash-damage exposure, mass centralized
  • Rapid Tuning System (RTS) for easy insert and spark-arrestor swaps
  • Quieter than stock with huge weight savings
  • Manufactured 100% in Southern California

Fitment: 4-stroke bike specific — fits the following models:

  • Sherco 250FSE (2018-2023)
  • Sherco 300FSE (2018-2023)
  • Sherco 450FSE (2020-2023)
  • Sherco 500FSE (2020-2023)

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
