FMF Factory 4.1 RCT Titanium Anodized Slip-On Exhaust with Carburetor Cap 042376 for Kawasaki KX250F

The FMF Factory 4.1 RCT Titanium Anodized Slip-On Exhaust with Carburetor Cap is engineered for Kawasaki KX250F models from 2017 through 2020. Manufacturer part number 042376 and vendor part number 79-40111 identify this application-specific exhaust system. Its titanium canister and mid-pipe provide a lightweight, durable construction designed for motocross and off-road performance.

Featuring FMF Resonance Chamber Technology, this tuned exhaust uses a patented core shape to reduce sound levels while maintaining strong power output. The patented canister shape increases internal volume for additional sound-absorbing material, while the chamber design helps refine exhaust pressure for optimized performance. Factory Forward Engineering centralizes mass and helps reduce vulnerability to crash damage, making the system well suited for demanding track conditions.

Installation and maintenance are simplified with the innovative rear end cap, which accepts tuning tip inserts or a spark arrestor. The exhaust includes a spark arrestor and wash plug for added versatility during trail use and routine servicing. The system is designed to fit 2017, 2018, 2019, and 2020 Kawasaki KX250F motorcycles. Professional installation is recommended to confirm proper fitment and exhaust system alignment.
