Upgrade your Kawasaki KLX140 with the FMF Powercore 4 Slip-On Exhaust, manufacturer part number 042160 and vendor part number 79-042160. Designed for riders seeking improved exhaust flow and reduced weight, this performance muffler features the latest Powercore 4 design with a high-flow core that provides increased surface area for sound absorption while allowing exhaust gases to move efficiently.
The FMF Powercore 4 is constructed with an extruded aluminum canister and a stainless steel midpipe secured with MIG/TIG welding for strength and durability. Space-age internal packing helps manage exhaust sound and withstand demanding riding conditions. The lighter, stronger construction delivers a performance-focused alternative to the stock exhaust system while maintaining a practical fit for compatible Kawasaki models.
For off-road use, the Powercore 4 S/A includes a U.S. Forest Service-approved, maintenance-free stainless steel spark arrestor screen. This slip-on exhaust fits 2008-2017 Kawasaki KLX140 models and the 2017 Kawasaki KLX140G. Verify your motorcycle model and year before installation to confirm compatibility.
