FMF FACTORY SLIP-ON SILENCER
The goal was to offer a lightweight, high performance exhaust system that also maintains a responsible
noise level. The silencer also had to meet the needs of both enduro and motocross riders. The result is
an all new design for the new generation of KTM’s. Based on the successful Q4 architecture from FMF,
KTM took it further by rigorously testing and tweaking in collaboration with FMF R&D. Wrapped in
a titanium skin, the final result is a lightweight, quiet exhaust with great performance. Includes
Removable Spark Arrestor. FOR CLOSED COURSE COMPETITION USE ONLY.
