Upgrade your motorcycle’s exhaust performance with the FMF Powercore 4 S/A Exhaust System, manufacturer part number 042005 and vendor part number 79-7233. Designed for select Kawasaki KLX110 and Suzuki DR-Z110 models, this complete system is engineered to provide improved exhaust flow, strong construction, and a lighter alternative to the original equipment exhaust. The system is compatible with 2002–2011 Kawasaki KLX110 models and the Suzuki DR-Z110 application identified by FMF.
The latest Powercore 4 design uses a high-flow core with increased surface area to help absorb sound while allowing exhaust gases to flow efficiently. Its extruded aluminum canister and stainless steel mid-pipe are built for durability, with precision MIG/TIG-welded construction and advanced internal packing for reliable performance. The result is a stronger, lighter exhaust system designed to support improved power delivery compared with stock equipment.
The FMF Powercore 4 S/A includes a U.S. Forest Service-approved, maintenance-free stainless steel spark arrestor screen. This feature makes the system suitable for off-road riding environments where spark-arrestor compliance is required. Confirm the motorcycle model, year, and mounting configuration before installation to ensure proper fitment.
