Upgrade the exhaust performance of your compatible Kawasaki motocross or cross-country motorcycle with the FMF 4.1 RCT Anodized Titanium Slip-On Exhaust. Manufacturer part number 042412, also identified by vendor part number 79-042412, this tuned exhaust system is engineered specifically for the 2025 and 2026 Kawasaki KX250F and KX250X. The FMF 4.1 RCT combines a titanium canister and mid-pipe with a carbon fiber end cap for a lightweight, durable design suited to demanding off-road riding.

FMF’s Resonance Chamber Technology uses a patented core shape to help reduce sound output while maintaining strong power performance. The patented canister shape provides increased internal volume for additional sound-absorbing material, while the chamber design helps refine exhaust pressure for optimized response. Factory Forward Engineering centralizes mass and helps reduce the likelihood of crash damage, making this slip-on a practical choice for riders who need performance and durability on the track or trail.

The innovative rear end cap simplifies installation of tuning tip inserts or a spark arrestor. This FMF exhaust includes a spark arrestor and wash plug, supporting trail-ready use and routine maintenance. Confirm your motorcycle’s model year and configuration before installation to ensure proper fitment.
