The FMF Mini Powercore 4 Spark Arrestor 4-Stroke Exhaust is designed to improve exhaust flow and performance on compatible Kawasaki KLX140 and KLX140G motorcycles. Manufacturer part number 042161 and vendor part number 79-1543 identify this FMF exhaust system. Its high-flow core provides increased surface area to absorb sound while allowing exhaust gases to move more efficiently, helping deliver stronger performance than the stock exhaust.
Built for demanding off-road use, the FMF Mini Powercore 4 features an extruded aluminum canister and a stainless steel midpipe with MIG/TIG-welded construction. Space-age internal packing supports effective sound control and long-term durability. The lighter construction helps reduce weight compared with the original exhaust while maintaining the strength needed for trail riding and recreational use.
The Powercore 4 S/A includes a maintenance-free stainless steel spark arrestor screen approved by the U.S. Forest Service. This feature helps meet applicable trail-use requirements while reducing routine maintenance. The exhaust fits 2008, 2009, and 2011 through 2017 Kawasaki KLX140 models, including the 2017 Kawasaki KLX140G. Confirm model-year compatibility before installation and follow the manufacturer’s installation and maintenance instructions.
