The FMF Powercore 4 Spark Arrestor Slip-On Muffler is designed for riders seeking improved exhaust flow, responsive performance, and reduced weight compared with the stock exhaust system. Manufacturer part number 041582 and vendor part number 79-2638, this FMF muffler is built specifically for the Honda CRF125F model years 2019 through 2026.
Featuring the latest Powercore 4 design, the muffler uses a high-flow core with increased surface area to absorb more sound while allowing exhaust gases to move efficiently. The extruded aluminum canister helps reduce weight, while the stainless steel midpipe is MIG/TIG welded for strength and durability. Space-age internal packing supports consistent sound control and performance during demanding riding conditions.
The Powercore 4 S/A includes a U.S. Forest Service-approved, maintenance-free stainless steel spark arrestor screen for compliant off-road use where approved spark arrestor equipment is required. Its slip-on configuration is intended to provide a straightforward upgrade for the original exhaust system while maintaining fitment for the specified motorcycle applications. Verify local regulations and installation requirements before use.
