Designed in aerospace materials with a compact architecture and an innovative RTS system, it offers significant weight reduction and mass centralization ideal for competition.
FMF offers you its high-performance Factory 4.1 RCT exhaust system, specially designed for Kawasaki MotoCross bikes. This system incorporates patented RCT (Resonance Chamber Technology), an FMF innovation that combines internal and external resonance chambers to effectively reduce noise while maintaining maximum engine power. Thanks to its optimized internal ducts, the exhaust volume is increased, considerably improving gas flow and delivering a constant power gain throughout the rev range. The Factory Forward Engineering design centralizes the exhaust mass, enhancing the bike's strength and handling in extreme conditions. The innovative exhaust tip facilitates installation of the spark arrestor or dB killer by simply removing four screws. Compliant with AMA and FIM noise standards, this line includes a 94 dB reducer insert and is made entirely in the USA from top-quality materials. Ideal for riders looking for performance, reliability and compliance.
